43folders is a name that actually makes sense. The one item of productivity pr0n that is t unique to GTD is the tickler file. An arrangement which consists of 43 folders.

Just for clarification, it's a rotating file with 31 folders for calendar days and 12 for months, 31 + 12 -> 43.

I'm pretty sure it also preceded the great majority of those domains.

Yeah.

The other big one, 37signals, is named after the signals sent into space in search of intelligent life. No clue re: 43things. All the other numbers exist because every other url was taken.

Didn't know that about 37signals. That's cool.

I think the other 43 domains followed 43folders, they succeeded it by a year or three IIRC.

Unique to GTD? http://en.wikipedia.org/wiki/Tickler_file

Perhaps not.
