I've been doing this for a while and didn't know it had a name. Sometimes I add an explicit snarky heading like this: TL;DR: <Main point> <Long explanation>

I've been doing this for a while and didn't know it had a name. Sometimes I add an explicit snarky heading like this: TL;DR: <Main point> <Long explanation> However, when writing comments on HN or other forums I go for what I call a "fireside chat" approach. Complete with metaphors, euphemisms and lots more sarcasm. Mostly because I find it more entertaining and enjoyable.
