In such a community, everyone should be able to share ideas. For everyone to look at. A site with ideas-up-for-grabs. It could become an idea database. If you share ideas that are good, and that get used, you could get some sort of credit or reward.
This is just an idea. One of the many concepts that pop up in my mind. Since there currently is no “Idea Space” that I’m aware of, I’m sharing the idea here. If you like it and have time, please go ahead, do something about it.
