More of a comment than an answer but it became way too long.
I agree with Neil, I like trying to help out on the site (not sure my efforts at reviewing are actually all that good, I skip quite a lot because I'm not sure what to do about them). Point is that questions and answers generally don't get that much rating on this site: it seems to suffer from a lack of voting.
For comparison I've asked 2 questions (and accepted answers) and answered 1 question on Skeptics.SE. I got more than 200 reputation on top of the starting 101: I'm about 303 at time of writing. I've got a pretty solidly positive record on Christianity.SE (1 closed question, 1 duplicate question, 1 question which after extensive editing I managed to get reopened) but after asking 26 questions (23 positive scored, 3 zeros), giving 12 answers (11 positive scores, 1 zeros) and doing plenty of edits, voting, reviewing etc. I'm at 1039 (at time of writing). To be fair I've burned 100 in bounties but 1139 doesn' make much difference. For the effort put in it is clearly much easier to get reputation on other sites. I've certainly poured 10s of times the time and effort into this site than over at Skeptics.
There is a natural through put of people on a site like this. I would imagine there are less than 20 regularly active members with enough reputation to work on close votes (and only about half of them actually seem to). This site due to its topic tends to build up a lot of bad questions. It's a problem. I don't know what the solution is, I certainly doubt that the standard stackexchange moderation reputation requirements will be changed just for this site but there you go.
