100x this. I am used to reading the traditional “write it in full once with a definition” for further use, eg. Breaking Bad (“BB”), but find lots of people on Hacker News just assume that everyone knows the acronym and several times a week find I have to search for a definition. It impedes understanding for what?
Hacker Newsers do this on purpose. Many believe that the fewer people that understand what they're saying, the smarter they will look.
Why waste time say lot word when few word do trick.
