Hi, thanks for the excellent feedback. Pics and vids are next up, via oEmbed. I agree there is much to be done about the layout. The noisy items in the right hand column are going at the bottom of the channel.

As for the selection of channels, we are seeing a lot of interesting channels set up by users, over 200 new channels only today!

Again, thanks! We'll try out different ways to increase sign up rate. A video or the possibility to create channels without signing up are great suggestions.
