Stephen Downes writes some reflections, Part 1  is all about techical terms in networks.

In Part 2 Downes writes about three viewpoint on the nature of communities in cities.
a, some say community is lost
b. some say community is saved
c some say community is liberated.
The descriptions of these viewpoints is worded in terms from part 1.

Part 3 Downes points out the loosely defined terminology in discussions on education. People should define their educational views in network terms as used in part 1.

Example

In a family the nodes are the members of the family. (node father, node mother, node son, node daughter, node baby)

The connections between the members of the family, between the nodes. The connections are called Links.

Tne node may have properties:
activation state. baby-node is not activated, baby sleeps.
number of connections. each node of this family has 4 connections to each other node.
activation function: what is needed to activate the node. Activating Node-son  is very difficult, the teacher says he is lazy.

In most families every link is two-sided.the link has two directions because Mom is speaking to Son and Son talks to Mom.
The strength of the link: Son and father node have strong link, they both like football.
The type of the link: father has father-links to the children and he is married to Mom.
The strands in the link. Mom is mother of Daughter, but she says she is also a friend. And mom and daughter are  partners in tennis. Mom and Daughter Nodes have 3 strands in the link. they are linked in 3 different ways.
