Well, right. So we're back to the starting proposition: That you shouldn't write a TL;DR if you didn't read the article.

Anyhow, this was more of a short blog post than a full article. It was a 2 minute read (not exactly a novel). And the thought experiments at the end are interesting, and illuminate some important points about how the language operates. Definitely worth the read.

I think their interpretation of "tl; dr" is: "it was too long so I didn't read it, and here is what I think anyway".
