Reputation for comments?
I suggesting to so a system that if your comments are up voted you earn some reputation, something like 1 point for each up vote or 1 point per 3 up votes(or something like this). Thanks.
Up to a point, a good idea. The rate should probably not be 1 rep point per up vote but smaller (hence 1 rep point per 3 up votes). There should probably also be a way to undo upvotes.
I like this in the sense that comments are still a "contribution to the community".
However, they certainly don't hold nearly the same value as actual answers, so you'd have to choose your point value wisely. Don't want rep-whores using comments as their new way to cheat.
