About the problem -- here's what Bob, our web elf, says about it:
"Jon, I figgered out that there's a corrupt record in the database. I'm trying to get direct access to the Db in order to blow it away.
Any page that has that record on it comes up blank. I added a bunch of posts to move it down in the stack, and sure enough, the second page came up blank, and #1 was ok (and full of my posts)."
So -- yes, we're working on it, and we're also very sorry for the interruption. And especially sorry for giving you fits, Freud. We'll get it all better really soon, and anyway -- you've come up with a temporary workaround. Thanks.
