Terrific idea. I'm not at my regular computer so I don't have the threads I've bookmarked, but I will try to edit them in later.
Some particularly strong threads:
John Kirk's The Time Is The Key thread
Tom MacWood's Bunker Quiz thread
Bob Huntley's thread on a profile in courage

The threads I'd most like to rediscover are the really old - circa 2001-2 - threads where we first learned about the magical place called Garden City.
