I'd like to see a showcase section of the community that allows members to post mini case studies of successful programs.
Ideally this would be somewhat structured to highlight features / methods used, provide links to live instances (or archived documentation if timebound) and potentially even start documenting code/flow steps, etc.
I wouldn't mind sharing some items to speed people up and would love to leverage when applicable - realizing that we use at our own risk and have to fit our individual environment - but why start from scratch!
