FYI - this was an interesting site I noticed earlier. Hoping that they get some traction...
The new Geographic Information Systems Stack Exchange site is now open to the public!
After just 7 days in private beta, we've already got 234 users who have asked 113 questions and written 327 answers. We're off to a good start, and it's time to unleash this baby on the public and see if it flies. (Sorry; mixed metaphor.)
Tell all your friends, blog about it, tweet about it, and write the URL (http://gis.stackexchange.com) in chalk on the sidewalk in front of your neighbor's house. Or paint. No, never mind, better use chalk.
Most importantly, go to the site now and start earning reputation and badges! We'll see you there! Right now!
All the best,
The Stack Exchange Team
