⚡Community Notes got faster, yet again. We just rolled out an optimization to the scorer that shaves 30mins of the time it takes notes to go live.

Under the hood details: we moved some of the computation (e.g. the initial matrix factorization) into a prescoring step, which…

Contributors’ time is valuable and best spent reviewing high quality notes. We just rolled out an update to boost the quality of proposed notes by making it easier for accounts to lose writing ability if their notes are found Not Helpful by people from wide-ranging points of…

✨Note writing limits now consider hit rate, a writer’s ratio of helpful to total notes written. To write many notes in 24h, a writer must have a history of helpful notes and a solid hit rate. This prevents large volumes of proposed notes that aren’t found helpful. Details in…

Starting today, you won't be prompted to rate notes if all notes on a post are already rated 'Not Helpful' or explain why a note isn’t needed. Saves contributors’ time so they can focus where ratings matter most.
