Who cars what other people do? If you don't follow people that retweet stupid celebrites its awesome. I get lots of intressting and funny tweets (or very short conversations) about poltics and computer sience. Don't blame twitter if you follow the wrong people.
Twitter is fine as it is for me, if the add other features they might be useful or the might not be useful as long as the main service dosn't change I don't really give a shit.
That said I dont belive that Twitter will ever be bigger then Google.
The problem is, even most interesting people to follow retweet random crap about their personal life at times, and when they do tweet interesting content, I sometimes want to have a conversation about it, which I can't do there.
