Cool, I just got an invite.
"Dear PlayStation®Network member,
Congratulations, you have been selected to help beta test PlayStation®Home!
We appreciate your help in making the PlayStation®Home experience the best it can be! Please log in to Home this evening from 6 pm - 8 pm PST for a big celebration of Version 1.0 and a load test of our new features. "
Kinda cool, I've been wanting to check out Home for a while now. The only problem is that this will cut into my Resistance 2 time. =(
