My need to organize!

I am a completely type A personality... therefore it drives me crazy if my bookmarks, folders, house, classroom, anything really, is unorganized. As a result, I wasn't completely happy with using Google Reader. After watching the videos on how to organize Google Reader, I now am much happier with using it. I have now organized all of the blogs and news feeds into tidy folders based on their subject matter. So far I have made folders titled: Science, News, Horse Stuff, Thinking Education, & World Cup Soccer. This has made it much easier to manage the clutter. I do have a question though, can Twitter be part of this on Google Reader too?
