Nik Fletcher on Apple’s Ping network:
A purchase of a song isn’t the strongest indicator of a user’s liking of a song: the playing of a song is. Ping with Scrobbling would offer me far more of an incentive to visit – I care much more about what my friends are listening to as opposed to what they’re buying (and even when buying, there’s no guarantee the purchase will be via iTunes and thus tracked).
What a great point.
