Yeah,I really don't get it.I tried it out and got pretty bored kinda quick.The only thing that I found remotely interesting was in the bowling alley arcade,they had that game Echochrome.I played that for quite a while.
At this point it would probably serve Sony best to just pull the plug on PlayStation Home and use those resources to improve their overall server capabilities.
I was playing Tekken 6 online,and the server is pretty much for shit.MAG beta that was out last week had it's issues as well,but I must say that I have yet to have one problem on MAG now that I'm in the IGN tournament,but that's mainly because there are only a handful of people online for that game now.
So if they did that and implemented a cross chat like XBox live has,and keep it free,then I think you would have a real winner.
