Speaking at the Develop Conference, Sony' Peter Edwards revealed that the return rate for PlayStation Home stands somewhere between 25-30 per cent, meaning that over 70 per cent of those who download and try the service do not return for a second time.

I have no idea if Sony is trying to put a positive spin on this ("More than one in four people who try Home become regular users!"). But considering it's free, that sounds like a lot of people aren't the least bit interested. Could it be that Sony's attempt to combine Facebook, avatars, and advertising in a 3D engine isn't a good idea?
