I like the community notes as a concept, but they're often a day late and a dollar short. By the time the community note appears the post has been squeezed of all of its juice and was already on the way out. It's better than nothing, but the entire mechanism runs slower than the speed of propaganda.
This. It's technically a solution but not a solution at all. It's like giving a calorie count AFTER someone's eaten a meal (or in this case after the tweet has been viewed by the majority of people that are going to view it).
They also don't seem to last. I don't know quite how it happens but you see a lot of these community notes disappear 24 hours after they appeared. They act on the tail end of the posts exposure and then are removed for the long term for when the news comes along and uses it as a reference. But all the people who spotted the misinformation see the post and the community note and so everyone walks away "happy".
