Apple refreshes iTunes software

Right now, many of you are likely downloading iTunes 10, the latest version of Apple's media software. The most notable feature in this new version is Ping, Apple's first stab at building a music social network (or really any kind of social network). It's interesting on a number of levels, but even the most basic level is pretty interesting: Ping's social graph. First of all, to use Ping at all you have to opt-in to it. While Apple CEO Steve Jobs touted the 160 million built-in users (it's currently available in iTunes in 23 countries), that's a bit misleading because many people won't opt-in to using it -- many of them for no other reason than they're lazy or just don't care. But assuming you do opt-in to it, the next social layer is interesting as well. Immediately, you're taken to a Privacy Settings page where Apple asks you how you'd like to use the service. This is where you decide if you want to use the friend model, the follow model, or the lurk model.
