Neat, but perhaps excessively artsy / pretty. The sliding moving interface is pretty fun to play with.

My peeves would be; the up/down arrows are difficult to find and control -- they shouldn't be hidden in the background. the lack of channels listed by order of popularity, no user count visible until you expand the channel details, and the text string: "Users: 4 Modes: [+ntr]" is easily misread as "4 Modes".

I would leave out the modes entirely, considering this interface is supposed to be "user simple". Instead, perhaps include plain language like "By invitation only" or "Requires a key to join"... only things that matter to the general public.
