Google Search   I’m Feeling Lucky




So Google is thought of by most people to be a search company. But it’s actually an
information company.

Even still, there’s no reason why Google shouldn’t do more to enhance its information
products with social information, helping to make more information that’s relevance, timely,
and useful available to everyone.

but there’s still a question about what this should really look like. And a question about the
right way for Google to get involved with and help advance the social web.

but in fact, there’s a much broader social story at Google — it just hasn’t revealed itself with
the same degree of obviousness that we see elsewhere in the industry.
In fact it’s important to keep in mind that Google’s original algorithm, called PageRank is
Google’s original “social web” product. How so?
“PageRank can be thought of as a model
   of user behavior.”




   Sergey Brin and Larry Page, 1998




Well, in the original academic paper that described PageRank, Larry and Sergey said that
PageRank “can be thought of as a model of user behavior.”
At the time, the user model that they were describing was that of a user following links from
one site to another — the “follow your nose” model of the “web of links”. From this kind of
user behavior, the algorithm for PageRank was derived (click).

While that model has changed over time, the basic premise that links indicate a social signals
remains relevant.

The signals that were once embedded in static HTML pages that could be crawled at one’s
leisure are now predominantly being shared in social streams. And more importantly, the
make up of social streams differs per person — which leads to an incredible opportunity to
improve personalization and the relevance of search results.

and so google can use those signals to personalize your search results, as they do with the
social circle feature.

which brings us to Buzz, Google’s latest baby entry into the social web.
This is what Buzz looks like in Gmail, in case you haven’t seen it.
it also gives you a nice way to interact with media right from within buzz.

Google Buzz and the social web
“ The best way to get a sense of where the Buzz API is
    heading is to take a look at http://code.google.com/
    apis/buzz/. You'll notice that the “coming soon”
    section mentions a ton of protocols—Activity
    Streams, Atom, AtomPub, MediaRSS, WebFinger,
    PubSubHubbub, Salmon, OAuth, XFN, etc.

    idea is that someday, any host on the web should

    users from any network, without any one

    messages can contain whatever crazy stuff
    people think to put in them. Google Buzz will
    be just another node (a very good node, I
    hope) among many peers.”

This is really important. The goal of Google Buzz, while on the one hand is create an
excellent social experience on the web, is also to adopt and make use of technologies that
expand the size and participation on the social web.

the goal is for there to be many different players on the open web, providing choice for
people, and competing to offer the best services around.

And this isn’t just for the bigger or more popular services. The goal is for a much larger,
more interconnected social web to grow larger.

The web is better when it’s social.

And that means that we want to make sure that every page and site on the web can offer
social functionality, and compelling social experiences.
What do I mean by social?




it’s about enabling new verbs on the web... verbs like follow, share, discuss, comment,
mention, like, rate,

I’ve seen similar signs all over the Mission, where I live.

found some positive successes.

OpenID
Photo by Teresa Stanton


OpenID is like a personal skeleton key for all your web accounts.

By using an account that you already have to sign up for another website, not only is it more
convenient, but you are able to start developing your own universal web identity — that, if
you CHOOSE TO, you can own.
Why is OpenID important?




* People use different identities for different purposes
* Ultimately choice and competition is a good thing to foster in this early landscape.
* With greater diversity of providers, publishers may see the potential for wider distribution
of shareable content.
* Digital identity is in its infancy now; the final chapter has not yet been written.

Now, unfortunately this is what OpenID often looks like today.
when people really just want this.

their goal is to get access to their account

To be fair, this is merely an uncomfortable transitional step along a much longer path
towards open identity on the web. it is a means to an end, but not the end that we seek.

so this interface — with all these buttons, is what we call the “NASCAR”, which is named after
the cars in the popular american racing sport.

the result is what we call the “OpenID NASCAR” where everyone wants their brand shown on
login forms....

But it’s this way for an important reason. People want — and exercise — choice when logging
in.
Contextual identity




And as more relying parties come online, it’s increasing important that there is choice in
identity providers.

For example, the OpenID that you might want to use to sign in to Basecamp may be different
from the one that you want to use to sign in to Lady Gaga’s website.

And that idea proves out in case after case.

Making OpenID easier

One of the biggest challenges is helping people to know what their OpenID is and to
remember it.

turns out that email addresses seem to be much more universal and memorable than an

use an email address as a way to bootstrap the OpenID authentication process. (more on that

Well, the obvious thing is import my address book and see which of my friends is already on

Think of OAuth like your valet key for the web.
On the desktop




let’s take a look at how OAuth works on the desktop using the Yammer Adobe Air app.
when you launch the app for the first time, you’ll be asked to authorize access to your data.
the app will launch a page like this in your browser and you click authorize.
the app will launch a page like this in your browser and you click authorize.

next you’re given a special code to prevent what’s called “session fixation attack”.
return to the app and enter the code
and now you’ve granted access to the desktop app without needing to provide your
password.

1999




RSS 0.9 was introduced in 1999 by Netscape as a content-gathering mechanism for My
Netscape Network (MNN) back when portals were all the rage (pre-social networks).

By providing a simple snapshot-in-a-document, web site producers acquired audience
through the presence of their content on My Netscape.
so, you’d have someone like the NYTimes wanting to grow their online audience...
...and they’d use RSS to get their content into the Netscape portal.

RSS looks like this.
RSS




                    title + link + description




the only mandatory fields in RSS are title, link, and description — which makes it an
extremely flexible format. The only problem is that aggregators have to do a lot of
guesswork about what’s in it.

this was complicated by the various flavors of RSS (0.9, 0.91, 0.92, 0.93, 2.0 et al)
2005




this in 2005, a group of people got together to create a “better specified” syndication format
called Atom.
Atom

here’s what ATOM looks like.
Atom




                      title + link + summary +
                       author + id + updated




so, in five years, the required elements of RSS essentially doubled, and we now had a unique
way to identity a feed entry, the author, and when it was last changed.
even still, this format was really still designed for the case of syndicating ARTICLES into
PORTALS.

and yet we know that people are performing more and more activities online.

and yet, regardless of its type, sites only publish this information as RSS or Atom
so no matter what, to sites like Friendfeed, Facebook, or Google Buzz, all these activities all
look the same.

so how do you differentiate all these different feeds when you only have one basic format?
actor verb object target




the basic model of ActivityStreams follows the “actor verb object”, “target”archetype.
Atom

       <?xml version="1.0" encoding="utf-8"?>
       <feed xmlns="http://www.w3.org/2005/Atom">

              </summary>

       </feed>




well, let’s take your typical Atom feed...
Atom




                      title + link + summary +
                       author + id + updated




remember that the foundation of Atom is title, link, summary, author, id, and the updated
time.
Atom+ActivityStreams




                   title + link + summary +
                     author + id + updated
                 + verb + object-type + target




now add verb, object-type, and target

so, see what this adds for the aggregator?

as the most basic example, we’re essentially telling the aggregator that a person posted a
note.

Connect



and so I before I joined Google, I proposed a simple idea built upon all these open
technologies called OpenID Connect that ties all these technologies that I’ve told you about
together.

This concept is emerging and I think you’ll see some exciting moves in this area this year —
so I want to leave you with that vision for the future.
Google Search   I’m Feeling Lucky




and when you think about Google and the social web, I think it’s important to really consider
where we’re headed.

and when you think about Google and the social web, I think it’s important to really consider
where we’re headed.
this is what we think of when we think of the social web, and the most exciting thing about it
[CLICK]

is that there’s plenty of space for you to establish yourself and make a name for your app.

  • 4. Google Search I’m Feeling Lucky So Google is thought of by most people to be a search company. But it’s actually an information company.

  • 11. In fact it’s important to keep in mind that Google’s original algorithm, called PageRank is Google’s original “social web” product. How so?
  • 12. “PageRank can be thought of as a model of user behavior.” Sergey Brin and Larry Page, 1998 Well, in the original academic paper that described PageRank, Larry and Sergey said that PageRank “can be thought of as a model of user behavior.”
  • 13. At the time, the user model that they were describing was that of a user following links from one site to another — the “follow your nose” model of the “web of links”. From this kind of user behavior, the algorithm for PageRank was derived (click). While that model has changed over time, the basic premise that links indicate a social signals remains relevant.

  • 16. The signals that were once embedded in static HTML pages that could be crawled at one’s leisure are now predominantly being shared in social streams. And more importantly, the make up of social streams differs per person — which leads to an incredible opportunity to improve personalization and the relevance of search results.

  • 33. “ The best way to get a sense of where the Buzz API is heading is to take a look at http://code.google.com/ apis/buzz/. You'll notice that the “coming soon” section mentions a ton of protocols—Activity Streams, Atom, AtomPub, MediaRSS, WebFinger, PubSubHubbub, Salmon, OAuth, XFN, etc. DeWitt Clinton, Google Photo by Joi Ito “The best way to get a sense of where the Buzz API is heading is to take a look at http:// code.google.com/apis/buzz/.

  • 34. “ What it doesn't talk much about is Google. That's because the goal isn't Google specific at all. The idea is that someday, any host on the web should be able to implement these open protocols and send messages back and forth in real time with users from any network, without any one company in the middle.

Google Buzz will be just another node (a very good node, I hope) among many peers.” DeWitt Clinton, Google Photo by Joi Ito “The web contains the social graph, the protocols are standard web protocols, the messages can contain whatever crazy stuff people think to put in them.

The goal of Google Buzz, while on the one hand is create an excellent social experience on the web, is also to adopt and make use of technologies that expand the size and participation on the social web.

  • 76. Photo by Teresa Stanton OpenID is like a personal skeleton key for all your web accounts. By using an account that you already have to sign up for another website, not only is it more convenient, but you are able to start developing your own universal web identity — that, if you CHOOSE TO, you can own.
  • 77. Why is OpenID important? * People use different identities for different purposes * Ultimately choice and competition is a good thing to foster in this early landscape. * With greater diversity of providers, publishers may see the potential for wider distribution of shareable content. * Digital identity is in its infancy now; the final chapter has not yet been written.

  • 86. Photo by Timothy Vogel the result is what we call the “OpenID NASCAR” where everyone wants their brand shown on login forms.... But it’s this way for an important reason. People want — and exercise — choice when logging in.
  • 87. Contextual identity And as more relying parties come online, it’s increasing important that there is choice in identity providers. For example, the OpenID that you might want to use to sign in to Basecamp may be different from the one that you want to use to sign in to Lady Gaga’s website. And that idea proves out in case after case.
