Redhen has been updating his Potterverse essays again, which make interesting reading. I don't agree with all his conclusions, but he's put a lot more thought into the Potter worldbuilding than all but the best fanfic authors - potentially useful, I suspect, for anyone writing a fic.
Personally, I do like his theories about Horcruxes and Snape, but even when you disagree, coming up with a good counterargument to a well argued essay can firm up your own worldbuilding in any fandom.
And, for the handful of people interested. I've updated my own Buffy fic, now including the swearing of mighty oaths, demons galore, and a long-awaited death - Si monumentum requiris, circumspice. There's only a short coda remaining before that story is complete, and I can think about the posssibility of a sequel.
