I joined Facebook

So, I joined facebook. It's a little overwhelming. I like blogger...I blog, you comment, I check your blog, I comment. EASY. Facebook has so many options. And what if someone asks to "Add as Friend" and you don't want to? I mean there are a few people that have asked me to "Add as Friend" and I see these people regularly, but I don't necessarily want to have them as my "Friend". Do I ignore them? or is it just proper Facebook etiquette to just "Add as Friend"? I guess it has enspired me to make a couple of posts here lately...that's good.
