Strong moderation with clearly defined goals and rules could go a long way, granted you had the resources to back it up long enough for it to become self-sufficient. Stack Exchange has some categories with strong moderation and rules. The problem with SE, in my opinion, is that posting there feels literally like working without being paid. There's almost no fun in posting answers on SE, while there is still a bit of fun posting on HN.
