Ah-fer-jayzuz-sake!

I have a question that I suspect a small number of you may be able to answer. I'm watching Buffy the Vampire Slayer at the moment (saw Enemies this evening ... um, yeah), and I want to find some decent plot analysis, commentary on continuity, etc. More specifically, what I really want is a Lurker's Guide to Babylon 5, only for Buffy.

I've done some Google searching. Results are sketchy, exhaustingly detailed and/or depressingly incoherent. So I turn to the all-seeing, all-knowing LJ. (Yes, stephencass, I am looking at you...) Any pointers?
