There's no use in interacting with posts, say, 8 hours old or so. Maybe less. Everybody has already moved on.
Edit: that's why I like the slower pace of the Fediverse, it's like the old messages boards I grew up with, with posts that simmered for days/months and there wasn't endless scrolling to steal your attention.
History happens every day, you just have more access to information to see it.
