 This section explores possible further applications in the social and knowledge spaces in the form of a series of short essays.

 - An Agora supports taxonomies in principle but mostly provides a set of basic tools to converge on meaning best effort through social processes based on federated [[heterarchies]].
 - [[Agora trees]], meaning by default [[outliner mode]] text with [[wikilinks]], hint at sections containing [[Agora Protocol]].

+  - [[heterarchies]], as represented by [[agora trees]] and [[path/like/queries]], can be reinforced by the Agora as more users hint at them.

 ## Collaborative world building
 - We seek to provision and maintain a distributed knowledge graph tailored specifically to the goal of solving problems: those of its users and society at large.
   - This [[knowledge graph]] will be a [[commons]].
