I am concerned about my privacy. That's one reason why I am not on any social networking sites at all (except for Twitter which poses no threat).

Rocker i understand your viewpoint and i agree with what you are saying.... my beef is (well would be if i was on FB) the way in which companies are doing this stuff.

Facebook has said that anything that you put on FB becomes "theirs forever". All your info (which is data they sell) all your pictures... everything. So let us say that you just now found out about this data mining they are doing... so you go to erase any sensitive info from your profile, is it too late? Do they already have that info now to sell? I'm not sure but i think it's shitty for a company to change their TOS and conveniently not tell their users about it. If they had said "On April 20th we will be changing our TOS and privacy settings to blah blah blah... if you wish to omit anything, do it before this change goes into effect" or something to that effect it would be much more respectable.
