The new design sucks badly. I've given it a go for a little while and I think its a major step backwards. Everything just looks so bland and boring now, as though all the content comes from Google, rather than individually creative users. The whole design is now dominated by these crappy pseudo professional channels, and there is nothing interesting anymore.
Each day I find my self wanting to come to youtube less and less -- I just can't be bothered with it now.
Its a pity, youtube was great while the fun lasted.
