I can't believe its not butter

This whole blogging deal is sort of interesting. I really am addicted to reading other people's blogs and look forward to the next update, and even get a little pissy when it is not soon enough. But where will MY blog go? What do I have to contribute to the blogging universe? I haven't really figured that out yet. I guess my blog identity is yet to evolve. Do you need a blog theme? Or is it ok to just mind stream?
