Apple says that more than one million users joined their new music-focused social network Ping in the 48 hours following its launch. I find that hard to believe. I do believe that people will flock like seagulls on a chip bag to a hot new social media site even though they can't keep up with the ones they're already on. I do believe that people will jump at the idea of a music-based network (take that Myspace!) especially one brought to you buy the maker of the iPod.
