It'd be amusing if there were a feature for forum users to suggest games that Touch Arcade might cover. Every now and then there are games that seem to be overlooked and with the popularity of users discussing "overlooked gems" on the forums there seems to be a demand. It could be helpful to both Touch Arcade, in identifying "trending" but overlooked material, and users in finding under the radar stuff. For example, Dungeon Plunder came out this week with no mention on the front page. There have been several cases of what I perceive to be quality games (granted taste is subjective) not being covered. Maybe the implementation would be difficult but it could be as simple as a sticky recommendation thread here.
See the header where it says "Home", "Reviews", etc? On the far right, it says 'submit tip'. Tah-dah! Not that anyone uses it, I don't think, but hey, it's there!
