This blog is being migrated to a new blogging platform (at last!). This is our fifth migration since 2006, so I expect a bit of reorganization of content. We're going on hiatus for a bit until the dust settles.
Heads up: all comments posted from now to the new blog's appearance will be lost. If you post a comment that's gotten lost in the transition, please re-post when the new blog is up and running.
