Ask PG: Leader board ranked my comment karma

I think comment karma is a much more accurate way of representing the quality of contributions a particular user makes. And I don't think factoring in submission karma really adds any significant value to assessing that quality. A lot more thought is put into sparking interesting conversation than submitting an interesting article, but often times, the karma doesn't quite reflect that, as submissions can get voted up to relatively high amounts, making any comment karma gain seem insignificant, and recognizing/rewarding users inaccurately.

So, an alternate leader board would be appreciated.
