The biggest problem for me is finding artists and people to follow. Why can the Genius feature look at my library and suggest music to buy but in Ping I get 14 suggestions that are all unrelated? Ok, facebook and apple are sorting things out, but why do i have to enter email addresses? Why can't it look at my apple address book and at least let me pick from that? Very messy rollout and I can't help but think apple's secrecy and control is going to burn them here.
