Reputation is more than karma, how can we represent that in threads?

There are some very reputable people around HN who aren't on the leader board. norvig, F_J_H, paulirisch, jeresig, for example.

There are also folks who game the system for their own purposes (http://news.ycombinator.com/item?id=2946470), though perhaps not be in keeping with the guidelines (http://ycombinator.com/newsguidelines.html).

How can one show readers more of this in the threads? Should it be shown? I understand the "level playing field" argument, but it seems like karma and reputation are not convergent.
