A lot.

I don't seem to value it at all.. I always let things like google, Facebook, Firefox, apple use my data and I put my first and last name and my location down to the city I live in in my XBL profile and I also put my first and last name in youtube without hesitation I also linked everything into my b.net profile.

Let's see, I use Firefox configured with NoScript, BetterPrivacy, AdBlock, Cookie Monster, Https-Everywhere, RefControl, RequestPolicy, and Web of Trust. I also refuse to use Google and Facebook. So yeah, I value privacy and security a lot.

To be honest, i wouldn't care that much if indeed (for example) Google would track all the searches i made on there. As long as they get their data, it doesn't affect me. Even all the Pronz hehe :p. I could also care less if Facebook would use my info for their own purposes. As long as i as a person don't get involved with any of it. It is important to me though, that only my Facebook friends could check my pictures and/or info like my e-mail and phone number. I'm not 100% sure that's the case, but oh well. Oh and about this anonymity on forums, i could care less. I don't necessarily want you guys to completely know who i am and where i live, but i posted my picture here a few times already, so i'm pretty ok with that sort of thing. I'm no internet a-hole. As long as most of my friends don't know i'm a Legendary Mything Member or whatever, on a off topic forum on a game website haha. Since, gaming or forums in general are still perceived as a thing for the ''nerds'' among us, it would kind of hurt my social status if people would know :P. So yeah.

As long as no one is watching me jerk off through my webcam I'm good.

How do you mean? Amongst other, casual internet users (like in this forum)? Or amongst large corporations like google and facebook which harvest data collected from you and others?

Very little at all. While I enjoy the prospect of anonymity, I treat all interaction with the internet as if I am representing myself in a public forum. Far too many people assume that a username is enough protection to unleash all the negative traits you hide from the rest of the world.
