Yes, there is a trail there for those who don’t manually curate.. and there are over 500 curators and many channels of curation for those that do .. choices are key there.
Discord is a chat app, as there is no way currently to do these things on a the Steem chain, when there is we will. As I agree we should rely on a third party app... but alas, it is what it is for now 🤷♀️
Curation in the volume we do would not be doable on a “comment in a post”, it just wouldn’t. We use the chain by resteeming the posts, making curation compilations, commenting on the posts and oh yes - rewarding people for engaging on the authors posts as we believe engagement is good for the chain too.
Thanks for the interest, going to get back to curating now...
