I played WGT a lot around last year's US Open contest, but got frustrated by the balky interface. If your Internet connection is not consistent and fast, the swing meter can be very frustrating.
Didn't they have a U.S. Open contest last year where you played and tried to get into the WGT U.S. Open? I think a bunch of THPers tried that and I still get weekly emails from them. Haven't played it since though.
