When you log in to a Stack Exchange site for the first time, you get a very confusing page (see below). The most prominent UI feature is collection of flair from all the linked accounts. My first thought is "OK, I'm signed in, this is just to let me choose which account to copy my profile from." But it's not--at the bottom of the page is the button I must click to actually create a profile. What is the point of this intermediate step? I already know that I have an account on the other sites, and if I didn't it wouldn't really matter would it? Is the point that it warns you that if you don't want to have your account associated you need to use a different OpenID? Is this really a concern for users?
It seems like this could be simplified. Move the create new account button higher in the page, or just list the sites but don't show the whole flair, or something. I find this very confusing.
