Thanks. I don’t know why people use obscure abbreviations and acronyms.

Arguably CTA isn't exactly an obscure acronym. It's multi-disciplinary - quite common in UI/UX design and marketing; and also decently common in any branched of software engineering that interact with these topics, like... web development.

I've worked in software engineering on Internet things for decades and I have not once heard or seen this abbreviated before.

I don't know why people refuse to look things up.

They think it makes them sound knowledgable.

I don't think that is necessarily the case. If you use certain words all the time, shortening them makes sense. They might just forget which abbreviations are and aren't common knowledge. You wouldn't get mad if people use PC, CPU, ATM and RAM, right? Even SSD would be fine on HN, but it probably wouldn't be fine outside HN. (neither would using "HN")

I don't know why people can't take 0.3 seconds to type "what does CTA stand for?" into their favorite search engine/LLM/text-message-to-a-friend. This is "Hacker" News, yes? What do hackers know how to do? Learn things, yes?

Oh, and I also don't know why this needs to come up on approximately every single post that has an abbreviation that someone doesn't know.

To be exact, it takes more time than 0.3s to type it, even for a fast typer.

I don't know why people can't not exaggerate things? Doing it is certainly making their message less reliable, not more
