Are they using Diaspora, beyond the joining part? If they want to post an update or a picture, do they post in both Facebook and Diaspora? I would imagine some active users post on both, and most users would just use Facebook. So the users of both will be annoyed to get double updates for some people. The users of one of them will wonder why the other friend knows more about their mutual friend. I can't see getting into Facebook space as a good thing. For example Twitter seems to have a different space, Instagram also seems different.
