Great threads? Or just well-known threads? The greatness is arguable.
It seems (to me anyhow) that adding a forum for these would result in 2 more places to look for a thread - is it in OT? No? How about archived OT? No? Hall of fame? No? How about archived HOF?
Oddly, I can summarize the best known threads in 1 post:
.999... = 1
The plane takes off.
Alternator sized beef is not "bulk."
btw, what determines when a thread meets this standard? Wouldn't it have to be archived first? Else, you'd move an active thread. Based on the number of posts? "what are you listening to right now" has a ton, but in no way do I think anyone thinks of it other than a large nef collection with little substance.
It's not too bad of an idea, just doesn't seem it'd work that well.
I do believe there's a wiki page out there somewhere that does point to some of the best known threads.
