I've often wondered why no social news systems support a so called "smart vote." We could get a quick estimate from a user's comment history using a Flesch-Kincaid test (technically this guesses at writing grade level, but close enough) and then incorporate that into the voting system by over-weighting high scoring users vs other users. The important part in gathering top quality social news isn't that everyone has a say, it's that we simply get good content. Of course the whole 'your vote matters less than his' thing could be disastrous for an online community.
