Every crank is a visionary, but not every visionary is a crank.
Some visionaries prove to be prophets and seers. Some have ideas that are bogus. Due to the nature of visionary ideas, this is most of the time unknown -- e.g. Julian Jaynes's bicameral mind.
A crank is a visionary whose ideas are knowably bogus: e.g. Rupert Sheldrake. (A charlatan is unlike a crank because he has no idee fixe, no vision -- he moves opportunistically. A conspiracist is similarly unlike a crank because it bites at anything that moves.)
Whether Ted Nelson is a crank is left as an exercise for the reader.
I'm a fan of standup comics and love when comics in podcasts (like Rogan and whatnot) start ranting about "clean comedy", which means "not using the bad words".
But: every comment in this thread that uses a bad word is at best misguided, while comments without bad words are informative and keep the general mood in check.
I know people tend to bypass word filters by occluding letters ("B*rcelona") while retaining meaning; but maybe a word filter would cut dang's work by $A_LOT %.
