I suspect that no one, no matter their education or skill, would be able to map the directions these threads take. They rarely, if ever, go straight, and then only for a little while. They're full of hairpins, loop-de-loops, roundabouts (mostly between two debaters that nobody listens to), s-curves, v-curves, z-curves, and a few more from the alphabet as well.
Anyone trying to document the path any one thread takes is liable to either go insane, get lost, or add to the problem. Or all three.

And about 75% or more of the forumites here tend to fit the first and last conditions perfectly.
I'm lost. I've gone to find myself. If I should return before I get back, please ask me to wait. Thanks.
