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 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.
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.

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.

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

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

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.

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.

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

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.

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.

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.
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.

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

However, the last thing that you want to do is ask for a user’s password. That’s information
that should only be shared between the user and their provider.
Fortunately, there’s an alternative that’s gaining widespread adoption.

198. 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.
199. so, you’d have someone like the NYTimes wanting to grow their online audience...
200. ...and they’d use RSS to get their content into the Netscape portal.

RSS looks like this.
203. 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)
204. 2005
this in 2005, a group of people got together to create a “better specified” syndication format
called Atom.

here’s what ATOM looks like.
206. 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.
207. even still, this format was really still designed for the case of syndicating ARTICLES into
PORTALS.

215. and now you know why the newsfeed looks like it does.
spot the similarity?
216. 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
217. so no matter what, to sites like Friendfeed, Facebook, or Google Buzz, all these activities all
look the same.
218. icons by Fast Icon
so how do you differentiate all these different feeds when you only have one basic format?
219.
220. actor verb object target
the basic model of ActivityStreams follows the “actor verb object”, “target”archetype.
221. Atom
<?xml version="1.0" encoding="utf-8"?>
<feed xmlns="http://www.w3.org/2005/Atom">
<entry>
<title>...</title>
<link rel=”alternate”>...</link>
<id>...</id>
<updated>...</updated>
<author>
<name>...</name>
</author>
<summary>
...
</summary>
</entry>
</feed>
well, let’s take your typical Atom feed...
222. Atom
title + link + summary +
author + id + updated
remember that the foundation of Atom is title, link, summary, author, id, and the updated
time.
223. Atom+ActivityStreams
title + link + summary +
author + id + updated
+ verb + object-type + target
now add verb, object-type, and target
225. Atom+ActivityStreams

<content type=”html”>
...
</content>
</activity:object>
</entry>
</feed>
here are the new parts.
226. Atom+ActivityStreams
<?xml version="1.0" encoding="utf-8"?>
<feed xmlns="http://www.w3.org/2005/Atom" xmlns:activity="http://activitystrea.ms/spec/1.0/">

<content type=”html”>
...

</activity:object>
</entry>
</feed>
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.

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.
