True; You can use it now but its a $10,000 minimum/month ad buy done on a CPM basis.
You can already use it if you contact one of the sales reps.
See .myspace.com/hypertargeting
I've been in contact with one of their sales reps, and I asked her about it and she didn't even know what I was talking about. The only thing she told me was that I could now "hyper-target" categories like video games, entertainment etc. Sounds like they're still well behind the times.
