It doesn't have to be about relationships - I have Facebook for that. An audience can be useful and a lot of fun. I get thoughtful responses to questions I posit and random insights that have affected my thinking. There's some off the wall stuff and that can be fun too.

I think Twitter has a perceived high barrier to entry. If you don't have any friends on it, why would you tweet to yourself? And if you don't tweet, why would anyone follow you?

It's all about who you follow, IMHO.
