What’s up with the 43 meme? I happened upon 43 Folders while reading the Robot Co-op blog.
This site is chock full of details about “Getting Things Done”.

43 folders is part of the system that “GTD” discusses as a way of organizing your days and months. 31 folders for days in the month and 12 folders for months in the year. 31 + 12 = 43! Interesting 43 Things might be useful for the planning process described in “GTD”. Hmm I wonder if there is a connection here?
