I would note that YouTube/Twitch content-creators create subreddits for a very specific reason: they ask their communities to share links to "relevant" content there, and to upvote the links that the community would most want the content-creator themselves to see. Then, when the content-creator feels too lazy to make real content, they instead start a screen-recording + video session, sort their subreddit by "top - this week", and start clicking through the posts and live-reacting to them.

It's in theory equivalent to a "share things for me to react to" Discord channel — but the fact that it's Reddit means that it has automatic chronologically-segmented userbase-wide voting rounds applied to the links, which makes it easy for the content-creator to react "blind" to a bunch of "interesting" things in a row, without needing to do any pre-filtering for things they haven't seen yet, or editing out boring things, or showing anything that would break content-guidelines on a livestream.

Does your software have an answer to this use-case?
