The way this blog looks is governed by a canned ‘theme’ which we get off the wordpress site. The reason we had to take the blog down briefly was because my previous theme was not safe – it ended up full of crappy spammy code, which was a surprise and not a pleasant one. The upgrade set the theme back to the default, and now what you see should be the newly chosen theme (which I kinda did on the fly, and on the basis of “Is it clean, can you see the archives, and do the old links appear to work? with much input from Jeff).
Anyway, I have to thank Jeff for finding and fixing the problems, multiple, because I would have continued to be cruising along, fat dumb and happy, without noticing that there was something seriously wrong. Also the site should run faster.
