I use it almost as a newsfeed for things like small artists I like releasing new albums. News that I wouldn't get otherwise.

It's really not a social network I think. Communication is not really different to YouTube comment feeds, where there are people with social standing leaving messages and literally thousands commenting with no hope of ever getting a reply (unless they're socially relevant themselves).

I can't shake the feeling of being part of the masses when I use it, with my role in it being at most leaving a +1 in someone's followers/likes/retweets. Way less interactive than an old school forum, or HN, for example.
