Perhaps tasks could be assigned karma award amounts by LW editors (Nesov, Eliezer, Louie, etc.), or even just one person who is appointed as the Karma Genie.
Some kind of democratic or market mechanism would more accurately reflect the value of tasks.
Also, there should probably be more incentives for gaining karma in general, as there are incentives for gaining upload ratio on what.cd. Rising through the karma ranks should give users special privileges that are actually desired.
The top contributors list on the sidebar could link to a page with the full rankings.
Currently, LWers get +1 karma for a comment upvote, and +10 karma for a main post upvote. But clearly, there are other valuable things LWers could do for the community besides writing comments and posts. Writing isn't everyone's forte. Why not award karma for doing productive non-writing things? It's probably not optimal that karma and the community status that comes with it are awarded only for the thing that myself and a few other people are good at. For example, I really wish LW could award karma to programmers for improving LW.
The challenge is doing it fairly, in a way that doesn't alienate too many people. But there might be a workable way to do this, so let's explore.
