I recently watched an interview with Mr. Brett Slatkin, Engineering lead of Google Consumer Surveys, in which Brett explains that he has only recently opened a Twitter account. He has been hopeful that he would be able to tweet from his own blog without having to be part of another service…the idea being that there would be this “decentralized social web that my node could be a participant of, just like email”. He goes on to explain that “social networking is not like that, Facebook accounts cannot talk to MySpace accounts and there is this real inter-operability problem”.
