I see this sort of post on other blogs from time to time. Usually the person in charge of the blog has decided to go with a new look because (a) they can now do more with their site or (b) they just wanted a change. I'm in a (to me) new category this evening. My blog has a new look and for the life of me I can't explain why. I haven't done anything, but my site looks completely different to me in Firefox (my browser of choice). However, things look more or less the same in IE and Opera, so you may not see anything odd. Or maybe it's just me. Who knows?
UPDATE: Okay, everything appears as normal again this morning. Anyway, Ed tells me this is the most boring post ever, which is an accomplishment in its own way.
