The main problem with facebook as a search engine is that you need to be a member and you can only search in facebook. The great thing about the twitter realtime search is that you can actually just search right on their front page. Another downfall of facebook realtime search for me and well for plenty of people I know is that facebook is blocked at my work so I will never use it, I don't use facebook now, though I do have a profile, but its not a good enough feature to bring me back to using it again.
