Ok, the beta is open to all here! Enjoy!

Stack Overflow, a site for building Q & A sites, has approved one for GIS. It enters public beta in six days.
Description: “Beta Q&A site for programmers, DBAs, Cartographers, Geographers and anyone interested in GIS professionally” To get to this point enough people had to commit to participate. Those folks can participate in the closed beta running now. Other efforts based on community participation (a Reddit-like thing for example) died due to lack of interest. If you want this one to survive, participate!
