Now I know a lot of us keep our profiles to those sites on private. So even a link to our profiles will keep most unauthorized people out (most, because with enough will and skill nothing is truly private online). Even so, I don't know about you, but my name is not "John Smith" and a simple Google search for my full name will return me as it's top results. Maybe I'm paranoid, listen to too many security podcasts, but I prefer to keep the amount of information about myself on the web to a minimum.
So my question to you, DICHeads: How do you control access to your personal information online? Privacy settings? Aliases? Don't sign up in the first place? Who cares, if they really want my info they'll get it any way?
As for me, my (admittedly leaky) approach is to separate the web into public and private sections which don't touch as much as possible. Private areas (Facebook) have all privacy settings at or close to max and I only approve people I've met in real life. In public areas (Dream.In.Code) I use aliases and even separate email accounts to sign up.
