I didn't see any mention of Favorite communities impacting the algorithm. If I remember correctly this was a big or primary contributor to how we we customized our home feed and now it's not even part of the algorithm?
Second thought. I don't think rich media should factor into the algorithm or how many replies the author gets. Engage is being used within a business context and some important questions or announcements shouldn't require rich media to rank of other's feeds, unless the intent is to have communications and PR staff to do all the posts for us and I think that defeats the purpose of the Engage as a community conversation platform. Factoring in rich media and how many reactions a poster gets makes this too much like Facebook or IG and I don't think that's what companies want for their internal collaboration and communication platform.
