With the new event catalog, I am seeing a lot of inconsistancies with the way events are listed. In some cases, listings for that event are just not showing up at all, even though the details match the event perfectly. We use Ticket Technology, which pulls their event data from the same place I presume eBay pulls their's - StubHub - so there is no reason why our event info should not match your catalog.
In other instances, some listings are falling into a catalog listing for the incorrect event.
The concern I have is how adversly these problems affect listing exposure. If we have a listing that is not being cataloged at all, then we lose exposure. If we have a listing that is being cataloged to the wrong event, then we probably aren't getting any exposure at all.
