r/Firefox is doing it right - The mods announced they were reopening the #subreddit, but made it so new posts could only be pictures of foxes or red pandas…then said if people wanted to post about technical stuff, to do it on their kbin.
THAT is how you do it. The subreddit is still there, but functionally unusable, and there’s direction to the new place. #Reddit
