Ping, Apple’s foray into musical social networking, launched to much fanfare in September. Since then, not a lot has happened on the iTunes-connected application. Why hasn’t Ping’s launch triggered a mass band exodus from Myspace? The answer is simple: artists can’t just sign up for artist pages, at least not yet anyway. When Ping launched, only a small contingent of mostly major label bands and artists were deemed worthy beneficiaries of band pages created under Apple’s supervision. Now, Apple is allowing users to create band pages via third party sites including TuneCore. Apple also just released a User Guide for Ping. Will letting more artists join the platform provide Ping with the catalyst it needs? More info on Ping here.
