If you don't like Facebook don't use it, it's that simple. Social networks need a critical mass of people to run, even a naive user would stop using Facebook when most of his friends aren't there.

Facebook isn't the first social network and it isn't the last. It gained the most momentum, sure, but it will eventually fall. The trend is already downward. Anything other than just moving on not using Facebook is half measure. If you're still using Facebook by now, either you are naive or misinformed.
