Will read the article, thank you.

In the past I've tried to use POIC system[0][1] but it wasn't really that efficient and the biggest 2 problems were search (mostly full text, I could find entry from a particular date quite easly) and portability - over time it becomes a big physical thing you need to store (I move quite often).

I agree with you about dividing (almost) everything into single pieces of information and adding to the system, but I'm still trying to figure out how to do this well.
