Well, it feels empty... the whole side bar is gone, the handy calendar and other such tools that would normally run along the side are all gone... I preferred it the other way, because content could then by placed along the sides. But of course, this is a matter of opinion, so I think that it should be optional, to be set in your profile, whether you want it displayed or not. This way, those who want the extra content can have it and those who want a cleaner right-there-is-everything-you-need-in-front-of-you look, can disable it.
