Like a Commonplace book but it's a thread instead (hence the name)!
Dump notes about something you're learning or are interested in explaining here.
Who knows, maybe somebody will learn from your notes, use/steal them, correct your understanding of the subject, and/or add onto them.
All subjects of any field from biology to logic—whether treated at an advanced, simple, intermediate, or fundemental/philosophical level—are welcomed to be discussed here.
