For example, I really wish LW could award karma to programmers for improving LW.
It can't? The programmers of LW should be incentivized to implement awarding karma to programmers. (Although I would deduct karma from whoever replaced the "Reply Permalink Edit" etc. with icons.)
Suppose PersonA did a ton of good work on Less Wrong and got 10,000 karma, and then donated all of that karma toward making some great project highly incentivized. This person has done two wonderful things - all the wonderful work and incentivizing more wonderful work - but they have 0 karma to show for it.
They have real-world karma to show for it. But if that isn't enough for you, they could instead invest their karma in the project, and get back some fraction of the karma voted to the project.
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.
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.
