I just listened to “Cornelia Street” again, and was reminded of the sound of windshield wipers. Do you have any other such “hidden sounds” you like?
Do you maybe have ways to make them easier to spot?
For some reason I find those sound in that song easier to catch when I listen in my car. Coincidence?
For federation you will only get new posts, posts get pushed to your new one, you don’t pull the history. So as long as you’re seeing new posts and comments you’re probably fine
