What is meta? ×
Meta Stack Exchange is where users like you discuss bugs, features, and support issues that affect the software powering all 134 Stack Exchange communities.

There is a large list of Stack Exchange clones, but it is very hard to find thriving communities (ie. low spam rate, high answer quality and good answer rate).

I think that seeing how these communities operate could provide insights into other approaches for running a Q&A site. We would be able to see the effects of different policies without necessarily having to experiment with them ourselves.

What thriving communities are based on the Stack Exchange model?

MathOverflow isn't really a clone (it's still on SE1.0!) but it's probably one of the best successes outside of the network. –  Jeremy Banks Mar 17 '12 at 13:15

ask sql server central seems to be doing OK AFAIK. –  Martin Smith Mar 17 '12 at 13:18

Haha yes, Math Overflow is an amusing case, given the recent ruckus about "draconian moderation policies" here. –  Cody Gray Mar 17 '12 at 13:23
    
@CodyGray: Yes, MathOverflow's moderation is as draconian as it gets. It seems to work for them, though. –  Robert Harvey Mar 17 '12 at 16:32
    
Draw 3 cards for Magic the Gathering seems to be going quite well too. There may be a few other SE 1.0 sites that have managed to maintain an active community –  Casebash Mar 17 '12 at 22:50
    
@CodyGray: And here is the draconian moderation again –  Casebash Mar 21 '12 at 11:06

"First time here? Check out the FAQ!" No link to be found :D –  U2744 SNOWFLAKE Mar 17 '12 at 14:05

@minitech: The FAQ link is at the bottom. (Gah, why does nobody read the FAQ?!) I must say, their "search" box is much more inviting than the one on SO. Nice and obvious and autofocused. –  Wesley Murch Mar 17 '12 at 16:40

Looks like Askbot. –  user164291 Mar 17 '12 at 19:29
    
Nobody votes on questions there. –  Verbeia Mar 17 '12 at 20:48
    
The really nice thing about that search box is that it doesn't autoexpand... –  Cody Gray Mar 18 '12 at 7:26
    
@mog And... I just learned that SO has a search box. –  Tortoise Apr 10 '13 at 1:27
    
@todofixthis - Note the "Powered by Askbot" notice in AskFedora's footer... –  Tortoise Apr 10 '13 at 1:28

Openstreetmap (OSM) runs on a Q&A clone. In my experience, the quality of content seems to be poor in certain areas.

GIS is actually an official SE site, not a clone. –  Diago Mar 17 '12 at 13:05

@Diago: I know, I meant to say it's the nearest SE site to OSM that is official. Although GIS doesn't have as many OSM questions. –  Ambo100 Mar 17 '12 at 16:16
