Once again, regarding this question on the main site. I haven't looked at it in a while, but at one point there were 3 votes to close on it.
I've been a member of Stack Overflow since it was first public, and don't remember close votes ever "expiring." Do they, and I perhaps just never noticed/knew? Because right now, there are no close votes, and according to the revision history, it never was closed and reopened.
