Seeing as it is getting a little crowded in the forums, I think it would be best to have a dedicated thread to suggestions so other topics relating to the game as it stands now will have more room to thrive.
So here are the ground rules for posting here:
1. Comments should always be constructive. If you can, offer suggestions on how an idea might be improved or more feasible.
2. Be considerate of how much effort your suggestion might take to implement. How will it effect the game, and generally how might your idea add to the game experience? Big ideas are fine, but make sure to provide lots of detail on how such a thing might work.
3. No bug reports. Bugs should be reported in the "Glitches!" topic. If unsure whether something is a bug, I would still recommend posting it on the glitches page first.
