I think this could be helpful in some cases as well… depends on the discussions being posted I guess.
I’d actually requested something similar here:
In our use case when I’d asked about this feature above, the first post is simply a discussion prompt so having that visible all the time is like you said becomes a bit “old”. We thought it will also encourage moderators/instructors to keep updating the post by including a summary every now and then and maybe adding more questions so the discussion seems “new” for every new learner and it’s not the same first topic post that the hundreds of learners have answered before rather it’s a continuous discussion so that even though many answered before there is still engagement and “change”.
I would like to add that it has been about two years where we’ve not had a single “me too” post out of maybe more than a total of 1627 posts and that’s because these topic posts in the category where we’d wanted to activate this setting is for discussions where learners are responding to prompts from the lessons they are taking.
Good luck @hoangviet with your marketing project!
