All the issues are converging. The commentators are pushing for their rights. The innovators are building the pieces (Microformats, APML, OpenID etc). All that's left is for the aggitators to force the issue.
Chris Messina is my hero. Read his latest post about the bill of rights and the issue of user ownership and control of their user data.

I alluded to this earlier, but according to danah boyd, there’s a lot of people who seem really to not mind leaving their profiles (and “internet friends”) behind when they jump sites or — heck — forget their passwords and have to start all over. Is the problem as bad as we, the prolific social networkers with “inhibited manifest destinies”, seem to think it is? Or is this just a problem with the early adopters who have thousands of friends that they seem to think to want to cart around everywhere while they increasingly find themselves with ever-diminishing amounts of time to even “play” social network anymore?
