We're mulling over some changes to how we manage our community. The two things we'd like to solve are:
1. encourage the community to help answer technical questions
2. facilitate more casual communication in the community (sharing, ideas, general discussion).
Currently we have the mostly dead mailing lists, this fairly quiet G+ community, and the fairly busy but somewhat neglected community.createjs.com
The latter is doing ok, but isn't in a format that encourages either of the points above, so it mostly winds up with my team trying to answer questions when they have time. With the continuing growth of the community, this means that questions are being neglected, and we're spending more time on support instead of ongoing dev.
We're considering moving all technical questions to StackOverflow, where we've already seen a lot more community involvement, thanks to their karma system. It also does a better job of exposing previously asked questions, both on the site, and via search engines.
In parallel, we're considering setting up a sub on Reddit for general discussion and community interaction.
Issues would continue to be tracked on GitHub, and of course this G+ community would live on.
