I think you have some mistaken generalizations about how people use Facebook. Some people might use it as you describe, but for me, it's more of a personalized Twitter + event management platform + email replacement for people whose email address I don't have.

I took it that the point of the post is that even if you don't have a Facebook account, any one of your friends, co-workers or acquaintances could have imported their contact info into Facebook, you included, like it or not.

So how do you know that your friends have not uploaded your contact info or tagged pics to Facebook?

I don't; I'm just guessing, I suppose. That's a good enough point that I'm deleting my original post.

Why don't you like people who do that?

(Genuinely curious)

Just my personal neuroses. I'm not saying it's a rational thing, but fact is, I don't.
