Lost no more?

Google Maps is bringing its helpful blue dot indoors, so you'll be able to figure out where you are relative to where you want to go inside as well as out. While it looks like it just has some major airports and shopping areas mapped out as of now, I'm sure it's just a matter of time before you can use it at New Orleans' Morial Convention Center, or even better, Gaylord Opryland. Though with more conference organizers including interactive maps in their show apps, maybe this will be not quite so needed by the time Google gets around to major convention sites?
