My Lands: Black Gem Hunting

If you come up with a really good idea on here you get an artifact. If it's a really good one you get a level 5 or if it's not so great but it's implemented then you get a lesser artifact

That would certainly stimulate, this section of the forum

If not an artifact then it could be part of a quest called, 'the dawn of enlightenment' for example where you only get to start it if you come up with a bright idea on the forum.

It might be possible, but only if those ideas are really good and only after they were introduced into the game as upgrade.
