About 19 hours ago, I edited the featured tag out of a question and into another. About 7 hours ago, I made a few other small changes. The sidebar still hasn't updated to list the new questions.
I'd normally just blame caching, but the sidebar cache expires after four or six hours, so it definitely should have refreshed by now.
I'm getting antsy for someone to blame for all the horrible things in the world. Does anyone know what's up with sidebar refreshes?
