Saved with the link. Notes from 2007 to 2016 are mostly the page's own words, so this is probably an excerpt.
Tent is decentralized, not federated or centralized. Any Tent server can connect to any other Tent server. All features are available to any server as first-class citizens. Anyone can host their own Tent server. Tent servers can also be run as Tor hidden services to create a social darknet for at-risk organizers and activists. Anyone can write applications that connect to Tent in order to display or create user content.
