Hum. All that I'm looking for is a kind of large backlog that I could filter to find ideas that will improve the world that demands people, development, etc. These ideas could just come up with a description, motivation and expected results - when someone could help, he subscribes and notify the watchers.

Maybe a recurring thread (Idea Sunday) is not the best option for that as dang said (please, who disagree make your point). It seems that the better idea is to come up with a platform to bring these ideas to life, but a faster way than building from scratch would be nicer. Again, if you (who is reading it now) have any ideas, them will be appreciated.

I'll check out the links you sent below. Thanks for answering.
