No, discord threads are siloed off into their own world. They're effectively more so temporary channels (and discord itself enforces the temporary nature - they get locked after disuse). Parent poster seems to like it, but for my use case I'd rather slack threads.
I wasn’t commenting about liking discord threads. My comment was focused on how you can “inline” reply in discord, while you can’t do that in slack (though someone mentioned that you can post your reply to the main channel in slack - a feature I’ve never noticed or seen used).
Yikes, here's hoping you mean "after a year" or something, because having to make a fake new thread just to comment on an existing locked thread would make me rage quit
Someone with the manage threads permission can unarchive it, but like the pinning thing that also comes with permission to delete it, so you can't just grant that to everyone in your server.
Then that squares with my mental model of discord being for the gaming community, because imagine one's surprise about coming in to work on a Monday to have something to add to a thread made on Friday but unable to contribute to it. Or, what's this "vacation" stuff I keep hearing about?
