It's getting kind of close to ten thousand posts. Found this for potential commemoration:
Likely as not when the actual five digit post happens I'll totally not notice--asking somebody for their CS ticket number or confirming a factoid from staff. Just pointing out (with a hat tip to the creative/sick artists and taxidermists of the Internet who make squirrel jokes so abundant) that at the rate things are going it'll probably happen next week. Maybe during the raid.
Cheers and happy gaming!
