In less than two days, Apple's Ping music social network has surpassed the 1 million user milestone.
Apple introduced Ping as the centerpiece of iTunes 10 at its music event earlier this week. It is a music-centric social network where users can follow updates from both their friends and their favorite music artists. It includes custom song and album charts, a news feed and 17,000+ concert listings.
Ping has had a rocky road since its launch late on Wednesday. Apple's social network has been hit with comment spam and international availability issues. The company's in up-and-down talks with Facebook over integrations and API use. It's also received lackluster reviews from the media.
However, that hasn't stopped droves of people from trying out the iTunes-based social network. Apple says that 1/3 of users that have downloaded iTunes 10 have joined Ping.
