I guess that's why I don't "hate" Facebook, all I use it for is keeping in touch with family; maybe a couple of groups. Don't see much reason to hate it besides privacy concerns, (in my opinion) since everything else on the Internet is essentially stalking you one more thing isn't going to matter.
Heh, yea... but I guess to explain some of the 'hate' is that it frustrates me that so many people use such a bad platform for many things that almost force me to use it too. For example, some services and companies use Facebook pages or groups to conduct their communication (in place of an on-site forum... when FB is pretty much the worst forum software ever devised!), or people put Facebook based comment systems on their websites/blogs, etc. It's kind of hard not to use it or have an account. And, then there are those friends who pretty much use it alone, so you have to be on it if you want to keep in touch.
It's a love/hate thing for sure.
