Found an interesting, small little web application called LoanBack (found via O'Reilly Radar).

This site does one thing: it creates a custom promissory note for anyone who wants to lend/borrow money between friends or family. You answer a handful of questions, and a professional note is produced, complete with payment schedule.

I like finding sites that fill a specific need by doing one, straightforward thing. LoanBack has plans to add features, but I hope they keep the clean, simple process intact.
