I'm calling this a bug, but there might be a reasonable explaination. The question doesn't seem to be anything special but fairly regularly it seems to be bumped to the top of the queue by the Community user. There never seem to be any new edits or other reason for this question to come back in view. Anyone know why this happens?
Caleb answered why this happens. So I guess we ought to figure out how to clean up the question so that it can be answered. Or answer it. Or vote up one of the answers. Or close it.
I've done two of the four, now. Let's see is anyone will do one of the other two...
