@ntnsndr as @laurenshof says, a lot of low-hanging fruit. I'd suggest one start would be an audit of the Mastodon UX to make it more community-forward.
Examples from the 🐘 UI:
* "🌎 Live feeds" is where your local, chosen community is—how is any first-time user supposed to figure that out?
* I thought I signed up for the "social.coop community"—why is the logo at the top "Mastodon" and "social.coop" greyed out?
* For me 📣 means protest (or noise). Here: it is the most important community news?
