Apparently Ping hasn’t quietly died yet
What took you so long? Apple has linked up Twitter with Ping, a move Steve Jobs should have made before he ever launched his social music service. So now Ping users can tell their Twitter pals about music they like, and use Twitter to find other folks who might be using Ping. Ping still has a long way to go–most important, it needs to integrate directly with Facebook–but if it has any chance of working, this is an essential step.
