IMHO facebook is still as evil as ever!
Their sole purpose is harvesting your personal information to sell at a profit to whoever wants it with no known social responsibility.
If you're OK with that, go for it, but, as for me, I'd rather do without the information.
Luckily, you can still get into most facebook sites without being a member & harvest what you need,
but I understand that still opens you up to some extent to their data harvesting operations. (I'm not sure exactly how?)
