It seems like a good thing to reward useful contributions to Meta, but probably not as much as useful contributions to Q&A. I have mixed feelings about negative scores for downvotes, but bearing in mind the use of downvotes to express disagreement with good-faith proposals I'm inclined to remove them.

To have a concrete proposal for a starting point, I suggest:

* Meta question: up +2, down -0
* Meta answer: up +2, down -0
