Does Anyone Use Ping?

I've been using Apple's music social media network, Ping, since it first came out and I am not sure that it is relevant. I've found that all of the artists and bands that I follow post the exact same thing on Ping, as they do on Facebook and/or Twitter. They have improved some of the features of Ping since its debut and adding features such as concert listings and link up to Twitter, but it is definitely missing something… Has anyone else tried Ping?
