Well it depends on your goals with the platform. If you want a one stop shop to get all the necessary information in an efficient time then megathreads are great.
Nobody on Reddit, Lemmy, etc. behaves that way. Nobody checks megathreads unless it’s an ongoing, high profile situation. I guarantee you this megathread is going to get essentially no engagement within 48 hours and now for some odd reason all news about SpaceX, Twitter, and Tesla is functionally banned.
