One of the things I enjoy doing on Twitter is posting up something I'm working on, and then clicking through to all the profiles of the people who like, comment, or retweet my work. I stumble across an incredibly diverse range of people by doing this, many with conflicting opinions to my own, and many who belong to strange subcultures that I don't understand, but who were all drawn to my work for one reason or another.

I think there's definitely a danger of crafting a bubble for yourself if you choose to use it that way, but as a tool for discovering people making cool stuff who otherwise wouldn't cut through the noise on something like Google search, I haven't found anything better.
