An analysis of sexual assault on Buffy the Vampire Slayer which is also in large part a defense of how Buffy/Spike was written in S7. I find this meta particularly interesting since butterfly isn't a Buffy/Spike shipper, and while she's not anti-Spike, she doesn't count him among her favorite characters.
Speaking of people who aren't Spike fans, I hope I don't have to hand in my Spuffy credentials if I say that my favorite post about Seeing Red is this one, by coffeeandink, who is not only not a Buffy/Angel shipper, but, by her own acknowledgement, hates Spike.
Also, I found DeadLetters, a website of short BtVS and AtS fics that take the form of letters written by characters who have just died. I haven't had a chance to read all of them, but my favorite so far is you, me and shania twain, from Faith to Buffy.
