Hi guys, Dan here from TicketStumbler. While it was kind of PG to post this, there's still a long long way to go. Fansnap has done a good job with their maps and including many ticket sites (even if most of them post their tickets on Stubhub and Ticketsnow).
We've had a recent run of press recently (Financial Times, Boston Globe, Local News, ABCnews.com) and our interactive maps have been a huge hit, but we're not even close to having breathing room. Aka me on a tropical island drinking, Tom in Australia floating between cities.
