Twitter and Facebook are targeting different needs and communities, whether they know it or not. With Facebook you can find out what your friends are doing, but not much else. This is great for people who have a small and cohesive social network that largely communicates among its own members (e.g. young people.) Twitter is more of a broadcasting platform; you can learn what your friends (and random people you follow) are eating for breakfast, but you can also get the latest news out of Iran or the most recent viral meme that everyone will be blogging about tomorrow. Everyone seems to think "real-time updates" is a single category, but Twitter and Facebook each seem to be better at different facets of this info stream and I am not sure that either will make much of an inroad into the other one's turf.
