Twitter's value prop is a flat audience of "the whole world". More and more, I see value in smaller groups in social media. The only good part of Facebook is Groups and Events. People talk about information or social bubbles, but on Twitter you still have bubbles. Any social group will form bubbles as soon as they start fighting about something. Having a flat view of the entire social graph does not prevent bubbles.
