As some of you know, there's a folksonomy web application called 43things. It's a web site that lets you make goals and see the other people that also have the same goal. It's a goal setting website, and you can see what everyone else sets their goals as.
Now why 43? It seems to roll off the tongue pretty well, but I just ran across it today. 43 Folders | Oh, yeah...the name explains that in comes from the number of folders in a Tickler Filing system, where you have 12 month folders and 31 day folders, for a total of 43. Clever.
