sounds like a solution in search of a problem. the ticket selling platform is esy, there are dozens of people doing that, but ticketmaster has a contractual lock on virtually all big venues and all big acts.

I think there's going to be a lot more of these sites popping up in the near future. Someone's got to take down that monster.
