Well, I'm sure you guys can check logs and see which menu bar links are more popular than others .... I'd hate to see something popular whacked (I'm a fan of the "New Posts" link myself) .... but I couldn't imagine that User CP was popular enough to be so prominently featured. Too me it seems more like a utilitarian function rather than a daily use feature.
Sorry if I'm being annoying, I've sat through enough usability studies in my life that sometimes I tend to think in links and clinks. I know that whatever you guys work out going forward will be awesome!
