The solution is simple. Don't do Twitter, Facebook, and the other major social network sites. I only do Wrong Planet, and I sometimes post comments to Dear Abby. Anyone I really want to contact outside of those two sites, I reach by way of email, snail mail, phone, or in person. I see no need for anything like Facebook, as email works great for online contact. I have no need to keep up with every little detail of other people's lives, or for them to keep up with all aspects of my life. I would find the first very time consuming and time wasting, and the second one very time consuming and invasive of my privacy. So drop the big social sites already, and just use special interest sites, like this one, and emails, too.
