Ping had 1 million users milestone after two days of it’s launch. People using Ping were found reporting of receiving fraudulent messages for some days. The first and foremost thing that flashes into my mind was the security issue. And in Monday the spams of fraudulent messages were cleaned up.
No doubt it has many users that run in millions but it is not without criticism as well. People complained that Ping does not analyze a user’s entire music library. Instead, it only considers items that were purchased through the iTunes Store.
Ping has also been criticized for its lack of connectivity with other, larger, and more established social networks like the FaceBook and Twitter. Although Steve Jobs has dropped joining FaceBook because it demanded some terms that Apple cannot accept.
Hope Apple will solve problems one by one and try to achieve those milestones for which it is known.
