Since I started using del.icio.us, I went a little bit mad with the power and gobbled up oodles of fic at once. I am keeping track of the stuff i enjoy here, but so i feel more productive, here is a list of stories you ought to read:

Her Majesty by executrix (Wash(/)Simon, crew)
jolly good fun. executrix has a wonderful turn of phrase, makes me chortle out loud in glee.

White Rose, Silver Needle by Polly Burns (Mal/Simon, Mal/Jayne, Wash/Simon, Zoe/Inara, Kaylee/Inara, Kaylee/River)
excellent use of language - to manipulate, not just ornament, if that makes sense. very clever.

A Quiet Game by Runaway Scrape (Wash & Simon)
a lovely short story that comes together beautifully. very perceptive.

A Good Walk Spoiled by executrix (crew)
see above comments about the author's cleverness. this is so much fun, it really captures the benny hill-esque but also snarky humour the show really glowed with. I love it.

Like Describing the Alphabet by Mosca (Jayne/Mal)
possibly this story should go at the top of the list. jayne/mal isn't even a pairing i usually favour, but the characterisation in this is just *excellent*. it makes their relationship not merely believable, but quite strong with the way the author constructs and remains faithful to it. a fabulous read!
