> What IS (or at least could be) an interesting theme is "my adventures and fuckups trying to learn Control systems". You take the standpoint of a learner, a way-farer, and you write about what goes wrong, and occasionally, your triumph when things go right.

This. I'm long out of college and after thinking about starting a small blog for years I finally started one on github pages. Not to post super sophisticated articles showing how cool I am, but posts about weird problems or pitfalls that couldn't be solved through some googling. I try to describe the problem and failed approaches too, so should anyone ever have the same problem I hope I dropped enough keywords to help them find it.
