A taxonomy of ATmosphere applications

['Symbionts' use domain expertise to fill Bluesky feature gaps. Their survival relies on Bluesky growing without competing.]

['Offshoots' leverage Bluesky's userbase to construct their own separate communities.] Their permanence will come from their unique services — Blacksky Cash, Eurosky’s jurisdictional arbitrage, Cartridge’s single-minded focus on gaming. They get to play a positive variant of the old Microsoft playbook: Embrace, Extend, Escape.

['Cuckoos' create paid services on top of ATproto's shared architecture. They survive by leveraging the ecosystem without appearing a threat, and also by non-competition from Bluesky.]
