I vehemently oppose the new redditesque rule of "Begin posts with “TIL” ". One of the things I disliked about reddit is each sub having different rules, which also squashes Xposting ability, and Xposting is more common/important on the Lemmyverse since there are probably already 10 other TIL subs.
I reverted that rule away, but we can discuss it if you'd like 🙂
