final five recommendations
That seems to make sense to me. I'd like to use the "general non-profit expertise" as supporting material -- proof that other people do it and it's a good idea. But it should all be used to support the best few recommendations from the community (which we should refine to make better).
I think the best place to start is to flag a few of the best rewards in that category. Are there any of them that you particularly like?
(Note: a new thread has been started on volunteer recognition, asking for something a bit more specific.)
