This is great!
A boss at an old job used to track little nuggets of information in a Word Doc he called his "Master" file. It had everything from bugs he had discovered with rare microcontrollers, to short reviews of meals he ordered at restaurants. (The idea behind the meals reviews is that the next time he went to the restaurant, he could look up what he had last time and decide if he wanted to have it again, or try something different)
I never could get as hardcore into this 'knowledge logging' thing, but I've been interested in a tool like this for a while now.
