To be honest, I hate the new channels. I had the beta the night that one of the videos was uploaded, but I noticed something : it's harder to use than YouTube Channels 1.0. Why would I try to make my channel harder to use than it was before?
I put my channel back to the way I like it. I hope they don't force people to use their new channels. As someone said to me in a private message on YouTube, they're cheap rip-offs of Bebo. I hated Bebo too. YouTube better not make the new channels mandatory - I hope they leave you an option to revert it to a better layout.
