I still don't get what Twitter's value proposition is. What do you get out of it as a consumer? I remember how Twitter started. It was this obscure alternative to RSS feeds, that many news channels suddenly started pushing (why?). I remember how they would actively include a segment in nightly news on talking about what has been posted on Twitter, back when it wasn't really anything newsworthy. It did not seem like organic growth to me.
