I'm on MySpace because it helps me dig up performers in other parts of the country.
It's pretty bad though because if I have 1000 "friends" and I want to see which ones of them live in Florida, there is no wayy to performe that search.. There's no way to manage your friends at all. You can't alphabitze them or put them in any order.
If you were a promoter an wanted to invite local people to an event without pestering the rest of your international list there is no system to do so.
I still use it because so many people I need to meet are on it but it has serious flaws.
