When all likes lead to Facebook, and liking requires a Facebook account, and Facebook gets to hoard all of the
metadata and likes around the interactions between people and content, it depletes the ecosystem of potential
and chaos — those attributes which make the technology industry so interesting and competitive. It’s one thing
for semantic and identity layers to emerge on the web, but it’s something else entirely for the all of the
interactions on those layers to be piped through a single provider (and not just because that provider becomes a
single point of failure).

a massive personalized recommendation system

“Authenticated Pagerank”
Friday 21 May 2010
This sounds a lot to me like “Authenticated PageRank” — where everyone that wants to be listed in the index
would have to get a Google account first. Sounds kind of smart, right? Except — shucks — there’s just one
problem with this model: it’s evil!
