Facebook's bid to build the Social Web

There is a lot of controversy over Facebook's roll-out of out a new commenting system for blogs and third-party sites. Can you imagine every comment you make on blog posts, discussion boards or any other place where you post messages being linked back to your Facebook account -- and then made available to other websites, so those websites can personalize your experience when you next visit them?

It seems like Mark Zuckerberg certainly can:
This next version of Facebook Platform puts people at the center of the web. It lets you shape your experiences online and makes them more social. For example, if you like a band on Pandora, that information can become part of the graph so that later if you visit a concert site, the site can tell you when the band you like is coming to your area. The power of the open graph is that it helps to create a smarter, personalized web that gets better with every action taken.
