All I can say about RR's is that they're both terribly rewarding and terribly intimidating at the same time. I received a RR for the very first piece I submitted to the site, and I was literally paralysed with fear writing the next piece.
It took a while to settle down. I strive for perfection, and yes, I like my RR's, but I equally appreciate the time that mods and verifiers put into evaluating (and once, rejecting a truly crappy piece that ended up in the permanent round file) what I submit.
IMHO the whole system works well enough, aside from the occasional "revenge" score threat (so far, I've managed to block people fast enough for it not to happen) for not engaging in the "sexy chat" with some idiot who is reading something and sees me come online.
