If you stay up-to-date with what's in vogue among the technology elite, you've probably heard about turntable.fm. If you haven't, let me tell you: it's a website where you listen to music with other people. And when I say with other people, I mean it looks like your avatar is standing in a club with other people listening to DJs up on a booth. You can rate the song as "Awesome" or "Lame," chat with other clubbers, and even DJ if there's a free spot. DJs get points for awesome songs that let them get new avatars. It's absurdly addicting. And so the tech world has been abuzz with praise that has typically failed to see the really important lessons here.
