Curious about this one, what have been the longest threads (most posts)? I’m not so interested in GD or the other opinion-oriented ones as I expect them to go on forever. I’m more curious to see what the breadth and depth of knowledge has resulted in here in GQ or the Cecil or Staff Report comments…

Famous among some of the longest:
Are scalar weapons for real? (1017 replies)
What happens on May 33rd but only on leap year? (313 replies)
How to kill evil Nazi Groundhogs (270 replies)
It should be noted that some of the longest GQ threads, while addressing the factual question at hand, also contain a lot of joking about the subject in question.
Thanks! Anyone know if there were longer ones than this that have been lost to technical mishaps? Just curious…
The biggest cause of lost threads was the Winter of Our Missed Content - the boards were down for about a month and all the content from early December 2001 to the time the board went offline in February 2002 were lost. I don’t recall anything longer than the Scalar Weapons thread that was lost suring that time, though it’s not impossible.
Ah! they’re… never mind.
