Apple’s Ping just got 1 million users in 2 days. Granted they already have your email and credit card number, it’s still a nice launch that even the most promising web startups can replicate. Although initially spurned by Facebook, the companies are still in discussion. What other social components could Apple be possibly developing next? Location maybe? Game Center will perhaps have a broader and direct impact on connecting users through competition and also require a significant investment in infrastructure. However, the success or failure of Ping will be something others at the intersection of web and music will be paying close attention to. As a sign of life, Ping is already getting spammers.
