seeing as how skyscrapercity has one, and UT has grown so steadily into something that can begin call itself a high-traffic message board, it would be oh-so-convenient to have this...i'd pay $5 for it! would prefer it to be free, but oh well. i'd post waaaay more, and would use this for work and when i'm at city hall.
PLEASE! i'd even help make it. i work in GIS and would love to get some sort of spatial database going (like emporis) that can then be linked up with google maps..
