@mckinley@twtxt.net You’re absolutely right, that’s why I kept mentioning it as a personal preference. 😁
When I browse the web I almost entirely look for information with an “expiration” (tech and code related stuff tends to get old fast) and quite often if the topic is too outdated the only useful comments are the ones like “Hey! It’s been two years now, here’s a better way.” with some links to a newer page of some kind.
Of course I’m open to both cases to allow freedom of choice for everyone on how they want to handle that.
Another risk on a persistent comment system is to remember to have a way to moderate the posts, since you need to control what gets on your page and can potentially stay there forever.
