What I have always found interesting, is that people who do use Facebook are the ones that would click 'no, I don't have a facebook' in a poll like this. Facebook is the true definition of what it means to be a mindless sheep, while at the same time the user wants to blend and be a chameleon for whatever is going to make them feel accepted. Hating facebook is the GLP vibe, you get your votes, then go back to Facebook.
