From personal experience using facebook and twitter, facebook is a much richer source of information to be mined, to bad though that facebook is for the most part a closed platform, at least on the level that you get with twitter being able to analyse the stream of tweets or searching all tweets made. Wonder if people have created facebook apps for the sole purpose of getting access to a lot of users data then on sold that access to others? If that's even possible.
