Your comment brings me back to my first mirror making adventure, I was absolutely overwhelmed by the jargon and acronyms used by the mirror making community... a few years later I internalized it and use it as if it was common knowledge. I should put little explanations or details in my posts.
If you are a really big fan of something, you'll get familiar with the lingo, but that doesn't mean you can play StarCraft well or weld or shred your guitar.
That's actually part of why FizzBuzz was so notorious: there were (apparently) plenty of people who could talk the talk about programming and software engineering, but couldn't do FizzBuzz.
There was enough there for me to get the basic idea, which is fine I think. Can't really expect every niche post to have all the details necessary for a general audience and it's fun to get a glimpse into these worlds anyway.
