 			- Whereas a [[personal knowledge graph]] is usually maintained using a single [[personal knowledge management]] tool and stored in a single format, an Agora tends to be tool agnostic and support many formats as input.
 		- Being a [[graph]], an Agora can be defined as a set of vertexes or [[nodes]] `N` (entities) and [[edges]] `E` (known links between entities, optionally annotated).
 			- Agora [[nodes]] are defined by the set of known resources *about* the entity described by their title or other metadata.
-				- A [[node]] is a community maintained [[collection]] of voice-preserving individual [[subnodes]] defined by the resources contributed by a single user or group.
+				- A [[node]] is a community-maintained [[collection]] of voice-preserving individual [[subnodes]] defined by the resources contributed by a certain user or group.
 			- Because links between two nodes in an Agora can be [[annotated]] (i.e. #tagged or qualified by other nearby links) and have multiplicity, the Agora is in fact a [[hypergraph]].
 			- Individual agoras are expected to federate and organize into greater Agora networks, which are in themselves graph-like at a higher level.
 		- On a system level, there exists a [[reference Agora]] that provides a minimum viable implementation for the [[underlay]], [[interlay]], [[overlay]] components of the [[distributed knowledge graph]].
