Regarding the recent locked post: as the creator it is indeed your vision that you need to maintain. I do hope that you will consider editing the description of this community to clarify such for people in the future:
Manual curation of great Lemmy discussions and threads
Otherwise it made sense that it would fit? Perhaps... "please, no drama" or some such? Well, it's a thought:-).
Second:
if YOU think a post is worth sharing, that’s good enough
But if actual posts are not desired, only comments underneath those, that would help to clarify as well. Otherwise "discussion" can be ambiguous.
I hope this meta-discussion itself is of interest:-).
