There's a 'peer moderation' system in place: reviews, session reports and things like that get placed in the queue, and other users either approve or decline your submission. If they approve, then they can also decide on a GeekGold reward for taking the time to add content to the site, from 1 to 5. (GeekGold are the Fake Internet Points used on BGG/RPGG, which can be redeemed to buy an avatar, main badges and the trillion microbadges they have on the site.)
In the end, if your submission is approved (which I think needs more than 10 approvers), you get the average GeekGold award that the moderators gave you.
When I read an RPG book (and I do tend to read quite a few), I try to write a review of it if there are no reviews available or if I think I have something to add to the discussion. The review gets added to the queue, and when it gets approved (I've never had anything I submitted be declined), I take the GeekGold award as a measure of the quality of the review: if that's very high (and it's always high -- my peers are pretty generous), then that's an indication of what they thought of the effort I put in.
So my review of Monsterhearts 2 might be the best one I've written yet: it got a 4.9 GeekGold award!
That also might have to do with the subject of Monsterhearts -- it is very thematic and designed to explore queer themes. That makes it very much non-mainstream -- most RPG players probably won't play it (or even have heard of it!) but it has its fierce supporters. It certainly gave me a lot to think about -- and it's written with such wit and clarity, making it one of the best RPG texts I've ever read.
