So, I've been building a knowledge base (writing my own software for it as well), and this brings up an interesting question for me.

How do you (anyone) all feel Diaries help in personal knowledge?

Eg, I like the idea of keeping an informational log of each day - but I'm unsure what use can be obtained from it. Is there something inherent to a Diary that is better than, say, just adding some birthday information to "Becky"'s information in some type of personal knowledge base?

The best I can figure is that writing helps memory - but part of my knowledge base is being written with spaced repetition quizzing, so writing it into a knowledge base, vs a diary, seems just as effective.

To be clear, I'm just seeking discussion in this scope - I appreciate all attempts to build tools for our daily brains. I'm very interested in this landscape! Thank you for your work :)
