Dan, that you are Jewish makes your participation in that site worse imo, but naturally I don't suggest that that is your goal. Wikipedia Review is small enough, and the participants connected and familiar enough with each other for you to be considered to be involved in a joint enterprise though. You could easily achieve the same aims at another site, with a different focus. But one suspects that you feel your voice would be lessened were it not attached to the notoriety of WR.
Cla68, I'm well aware who contributes to Wikipedia Review. I'm sure you're all nice to your mothers too. I don't need examples of Wikipedia's being improved because of WR, because I don't dispute the value of a critical site.
