The Very Last Thing I’ll Write About Twitter  
Disclaimer: I never "got" really Twitter. The service still strikes me as mostly useless.Now this could just be me but he says:"Twitter needs to decentralize [...] my belief that all communications media will inevitably be decentralized, and that all businesses who build walled gardens will eventually see them torn down."So I heard we had this decentralized way of sharing which they call "the web" which is completely decentralized and without walled gardens. And we had these technologies called RSS and ATOM for receiving updates on those.So...he's effectively suggesting we go back to the web and RSS but with everyone writing shorter messages?
