If you sort on Lemmy by activity you can get exactly the same behaviour.

Point. That’s not the default behavior, though, and most users aren’t using the site that way - and I’d argue the site isn’t designed the be used that way, and that’s why most users don’t use that functionality.

And bumping is even often frowned upon because it pollutes active discussions. It’s just people abusing how those forums sort threads.

Not what I meant. I don’t mean people making worthless “bump” comments (that often just gets people banned) I mean that forums bump up threads that get new comments.

I use forums, and they’re just different.
