First, earlier this afternoon, I tried upgrading to WordPress 2.3.2, being that it’s an “urgent security release” and all that. In the process, it incinerated my categories, and nothing I could do would convince it to create new ones. I had to pull out the MySQL backup I’d made before the upgrade attempt and downgrade to the 2.2 branch again.
Second, Technorati seems to have dropped forty-odd days’ worth of blog reaction data. I think that’s a glitch on their end — hooray for any mistake it’s not my responsibility to fix!
