The new top bar looks like a good improvement, but I think that at least the log out button and also the chat could return to a more prevalent place. Another thing that bothers me is that the quick link to privileges seems to have been removed. I kind of liked clicking on myself in the bar to see my recent reputation and such, although the new reputation looks cool. It does however get confusing with other sites being mixed in.
I'm sure we will all adapt to it pretty quickly, but please consider changing the position of some links, like moving chat, blog, and log out back to the bar itself. Thanks!
