All the Blockland = Minecraft people make my head spin, it's obviously a different system :S With that said, I give my full support, there's plenty of creative-minded people in the Steam community (some having come from Blockland from Steam before, or vice versa) so getting the game actually greenlit is definately a good move.
My only minor complaint is two of your chosen trailers, while they showed off the power of the game well, were still the Interiors and Terrain version of the game, and may mislead a few people :P
