There's no horizontal scrollbar, so with 640x480 you're not able to see the content fully; on the top bar, you still see the "facebook connect" icon fine, but you'd have to click "Login t" to log in normally. 800x600 loses most of the sidebar, which wouldn't be a problem if the search box wasn't in it. The "give feedback" triangle is quite large at that resolution, though.
