UPDATE: Looking over it again I see that the paper is much rougher than I realized. Apologies to anyone who read it.
As a sort of challenge to myself, and prompted by a deadline that Matthew Pianalto alerted me to, I've tried to write an entire paper almost completely from scratch this semester. It does incorporate bits of an old, unpublished paper, but not much of it, and what I have used I have also revised quite a bit. The paper is by no means finished, but I think it's far enough along to be able to benefit from comments from other people. So if you have any, please fire away.
