Do you have a source for this? I just use (or avoid using) facebook for totally different reasons than I use twitter. On twitter I mostly communicate with people I've never met and have little association with apart from shared interests. It's a great way of meeting new people. Facebook is for communicating with people I already know, many of who are actively searching for alternatives but because "everybody uses it" are locked in.
