Twitter's ongoing evolution from open platform to global media company has all kinds of ramifications for the social-media industry and for businesses, but it also has implications for users.
I also hate that Twitter has become so big now, and has turned into much more of a broadcast network than somewhere you can really talk to people (I think this is part of the appeal of new networks like Google+ and App.net). Most people never post anything to the network, they just follow celebrities or sports teams, and those kinds of accounts rarely interact with “normal” people. The idea of Twitter as a conversational tool seems to be dying.
