Acronym. Also written tldr, too long didn’t read.
Where it comes from
Began as a dismissive reply on forums and Reddit, telling a poster their wall of text went unread. It inverted within a few years: writers started adding their own TL;DR as a courtesy.
How it is actually used
The self-applied form is now dominant and the insult is rare. Placed at the top or bottom of a long post, it gives the one-line version. The semicolon is often dropped in casual writing. Its presence signals the writer knows the post is long, which buys goodwill for the length.
Examples
- "TL;DR: it was a DNS problem"
- "tldr — do not upgrade yet"
- "adding a tldr for the long one"
Can a brand use it? Safe for brands
Safe and genuinely good practice on long posts. Using it dismissively toward someone else’s writing is the original, rude sense and best avoided.
