While I understand what you're saying, I believe that would trip me up. I'm very much used to scanning for "Register", "Sign up", "Join" or "Create account".

I'm also unsure how much people really hate giving up their information. If anything, people are looking for places to hand over their information: Facebook, MySpace, LinkedIn, etc.

I think the problem is really that the more steps needed to convert your users, the more likely it is a part will give up before the end.
