I for one am glad that writers keep context in mind when writing things.
Otherwise your comment would have to be:
“SC = The state of South Carolina, one of the 50 states in the United States of America which is a country in the continent of North America and is often referred to as the USA, for people who don’t live in the USA.”
I think this is a good time to talk about one of my biggest pet peeves. Aggregators like HN, while extremely useful, remove context from the articles they link to. I think it’s extremely important for readers to read the links, after reading the site’s about page, and maybe quickly glancing through the Wikipedia, or bio page (of the author), if it exists.
Actively creating the context should be a skill we should be teaching children in school, since the Internet has made things that we would otherwise never have been aware of so easily accessible.
