I've spent some of this dark, rainy December afternoon doing some site maintenance. Quite a few cobwebsites are gone (some have been gathering dust for five or six years), and I've dropped the advertising links to my books. That made room for rearrangements: Hot Zone Sources is now in the right-hand column just under the Google search function, and other lists have been moved up or down.
I use the site as a workspace, and in theory all the links would result in frequent new posts. In practice, some are seldom visited; I leave them there because some visitors might find them useful even if I don't. If you know of sites that should be here (especially bloggers), please let me know.
