I'll second the removal of karma points, at least publicly.
There are some aspects of reputation systems which are useful for identifying misbehaving participants but I don't see any evidence of such use cases on HN. Yet the karma system encourages karma whoring which IMHO significantly reduces the SnR of contributions (both articles posted, and velocity and content of comments).
Maybe as a starting point the karma scores can be hidden from public view?
