Not OP, but the act of writing not only solidifies knowledge, but creates it

PG has been beating that drum for a few decades, and I’ve experienced it too

And knowledge compounds — knowing stuff makes you learn faster, which can lead to new jobs, friends, projects, etc

I’ve also found it gratifying when undergrads are reading and referencing posts I wrote when they were 13 years old

There’s something very nice and human about that

Likewise I learned a ton from Joel Spolsky’s blog when I was 22
