Before reading this, I had just revisited Describing Fediverse apps in ways people understand.
Are you aiming for a Wikipedia type neutral tone? If not, and we can advocate for the Fediverse more, I would not write that Twitter has an algorithmic feed and Mastodon a chronological one, but that Twitter amplifies hate and controversy, to keep you watching ads as long as possible, while on Mastodon people amplify your posts if they think it has value for the community.
