So you'd want them to cut the item in their budget that most directly rewards and supports their volunteer editors' work on the projects? That would seem to be unwise.
First off, how much of this is going to wikipedia editors and how much is going to other stuff? Honest question, I tried looking and I couldn't figure out which grants actually get approved.
Secondly, the number of editors peaked in 2007, as far as I know. Why does the money spent on grants and awards keep going up if the number of editors keeps going down?
