I think the comment system (on games) here at armor games is lacking and needs more of a boost, the way its currently situated is that you post a comment and that's it, (if its a good comment) devs wont see it, new players wont see it, and other players cant vote to rate is as a good tip/suggestion.
Do you mean initially..or after all the spam has drowned it?
I'm actually a bit for the idea of upvoting comments..but the one thing I'd have to concede is it would end up with the funny ones, rather than the actual helpful ones, being the "top" comments
in kong that does not happen very much, a lot of things that are helpful are up voted, a lot (but also funny stuff too), either way the players don't lose
