Can you just use normal acronyms instead of something like AFAWK? Why not AFAIK? Do I need to know every acronym there is on the internet?

Or just not use acronyms for standard sentence structure and non-specialised terms?

For example: "AFAIK the TLA is NFG for well written prose FWIW, NGL."

It is awkward to parse them and is infuriating when the author can clearly write well otherwise, because they don't use three- or four-letter-acronyms to replace standard sentence structures for the rest of their prose.
