"The basic guiding principles for deciding what to write up and post here are two-fold. 1. Interesting (to me?) alternative proofs of known results, or explanations of important topics that can be difficult for beginners to learn are fair game. (As the literature improves, I may augment postings accordingly.) 2. With all due respect to the role of Andre Weil in the development of algebraic geometry, nobody should ever again have to read Weil's "Foundations of algebraic geometry": EGA must be an adequate logical starting point for the subject. Hence, if there is an important, interesting, or useful theorem whose published proofs use pre-Grothendieck methods in such an essential way so as to render them impenetrable to later generations (or to me?), and if I have a need to understand why the theorem is true and consequently I figure out a scheme-theoretic proof, then I'll try to write it up."
