What do you think makes fluther better than other Q&A sites?

I am having a hard time decided on a Q&A site to stick too. I was banned from Yahoo Answers over a year ago, Answerbag drastically changed, and Blurtit seems very childish. I do like fluther more than the others now, because of the structure and look. The under-sea theme is really cute.
Have you tried any other Q&A sites? What did you think?
Is fluther your favorite?
