I don't really care much about (superficial) online privacy. Sure, I don't want my friends to know I'm into diapers for example, but I only make sure people can't accidentally find things
I delete my URL history, so for example dailydiapers doesn't show up, but hey, if you check my cookies and flash history you will find it.
As long as it's legal, I don't care if someone finds out something about me. As long as it's not accidentally.
I do have a small advantage. I'm a 4chan regular, so (it happened before) if a friend of mine finds a fetish site, or finds my porn folder, I can just say it's a source for pictures on /b/.
"lower" online privacy (companies finding out whatever I do) isn't that hard. I block all ads so external companies can't track my browsing (just how often I visit THEIR site) and facebook only knows my name and age.
