Home now, so replying, if a bit later than I thought it'd be :P.
I've read the criteria you used. I think it's great in that it seems to work really well for you, but honestly? I wasn't actually thinking of going into that much detail about the fics I rec. Well, not that kind of specific detail, I guess. Scores and numbers don't help me much with fiction, I think. I kind of tend to measure fiction by how it made me feel, whether it kept me reading it against all better judgement, that sort of thing. If I'm going to put out recs/reviews, I'm probably going to go for a touchy-feely, worded, rambling review.
When I think "rec site I will always probably want to go back to", I think Smart Bitches, Trashy Books. I like the snark, I like how they give letter grades, but still explain why something about a B or C book kept them reading. I like how it's so clear that this is 'just' their opinion, and I think I'd find it fun to write in something approximating that style so long as I was comfortable with it.
Do you want to move this over to email, btw? I've got some questions about the possible rec-list-enterprise (Recenterprise?? XD) to think through sort of waiting at the back of my mind, but they'd probably be argued better in email or something similar.
