Most of these points are reasonable for Facebook. They're just saying that if you don't like the idea of the "connections," then don't share any information. At least you've been told that that information will be publicly visible, period. The fact that they keep your data even after you delete it from your profile isn't unreasonable either. Did you really think they would destroy all traces of your data just because you have removed it from your profile? I bet Google keeps your emails after you delete them.

The only thing that bothers me is point 6.

> Facebook sometimes creates a Connection when you post to your wall. If you use the name of a Connection in a post on your wall, it may show up on the Connection Page, without you even knowing it.

This is a little sneaky. I wouldn't have a problem if the connections were just behind the scenes (ie: not visible). Then it would be no different from Google checking for keywords in your emails so that they can target ads at you.
