Designing Communities Like Ecosystems
What if community platforms were designed like ecosystems? Which species (roles, rituals, constraints) stabilize the environment. And which introduce chaos?
Most community platforms are designed like containers. Think your classic plastic tupperware container.
You pour people in, add a few rules, maybe decorate the edges with features, and hope something tasty emerges. Maybe a cake? When it does not or becomes a festering petri dish, we blame the people. They are disengaged. They are toxic. They are lurking instead of contributing.
But containers are passive, non (intentionally) living. Ecosystems are not passive and very (intentionally) living.
An ecosystem is a living arrangement of relationships, feedback loops, and constraints that quietly shape what can survive there. Nothing thrives by accident. Stability is not enforced. It emerges from balance.
If we designed communities like ecosystems, the first shift would be this. We would stop asking how to drive activity and start asking what conditions make certain behaviors inevitable.
Think about a healthy forest. There is no single dominant species shouting instructions (except us; but alas…). Stability comes from diversity of roles that counterbalance one another. Predators prevent overpopulation. Decomposers recycle what would otherwise rot. Keystone species shape the terrain in ways that benefit others without direct coordination.
Communities work the same way, even if we rarely name it.
Every stable community has a few quiet keystone roles. Not the loudest voices or the most visible experts, but the people who translate norms into action. The ones who welcome newcomers by modeling how to behave rather than explaining it. The ones who ask the second question after the obvious one has already been answered. Remove them, and the space does not collapse immediately. It slowly loses coherence before inevitable decay and collapse.
Rituals play the role of seasonal cycles. They give people a shared sense of timing and rhythm. Weekly prompts, recurring showcases, average time to response, predictable moments of reflection. Not because people need novelty, but because repetition creates safety. In nature, seasons signal what is possible now. In communities, rituals do the same. Without them, participation becomes sporadic and exhausting; surprise consumes creative energy. Everything feels optional, which eventually means nothing feels worth showing up for.
Constraints are where most community designers get nervous, but they function like natural boundaries. Riverbanks don’t restrict water. They give it direction. Clear scopes, visible norms, intentional limits on what belongs where. These reduce chaos by reducing decision fatigue. When boundaries are absent, people bring everything. Opinions, grievances, off topic promotions. The system becomes noisy, not because the members are unruly, but because the environment never told them what kind of life it was designed to support.
Chaos enters ecosystems when one species is allowed to dominate unchecked. In communities, this often looks like over rewarding a single behavior that is sharp juxtaposition to what the community needs. Only posting is valued, so people post without listening. Only experts are elevated, so curiosity disappears. Only growth is celebrated, so trust erodes. The platform did not create bad actors. It created incentives that crowded out balance.
Moderation alone can’t fix this, just as culling a single species does not heal a damaged habitat. If the conditions remain the same, the imbalance returns over and over.
This is why so many community teams feel like they are constantly firefighting. They are trying to correct outcomes instead of redesigning the environment that produces them. You cannot ask for generosity in a system that rewards self promotion. You cannot demand civility in a space that amplifies outrage. You cannot cultivate belonging if the architecture only recognizes visibility.
When you see communities as ecosystems, leadership shifts from enforcement to stewardship. The work becomes less about control and more about calibration. Who is thriving here and why. Who cannot survive here and what does that tell us about the design. What behaviors are naturally reinforced by the layout of the space.
The most powerful question stops being how do we get people to act differently. It becomes what kind of environment would make the behavior we want the most natural thing to do.


Oooh 👀 @Mary Jantsch, this reminds me of the great work you’re doing!
This framing is brillant - the keystone species analogy really clicks. What strikes me is how those quiet keystone memebrs often don't realize their own impact until they step away. I've seen communities where removing just one person who asked good follow-up questions caused the whole conversaton dynamic to shift. I dunno if we can design for that role intentionally or if it just emerges naturally from the right conditions.
