The Shape of Social Conversations

Marc looks at the shape of social media conversations to see who’s connecting, conversing, or broadcasting. Did you ever think about social media having a shape? Me, neither. Not until recently. The graph above shows the shape of the #DigiBlogChat hashtag.

Measuring the Shapes

“Networks are collections of connections. Social media allows people to author connections with one another – by liking, linking, following, friending, favoriting, rating, reviewing, replying, and sharing. In aggregate, these collections of connections have a shape. Network analysis is about measuring that shape as well as calculating the position of each person within the larger structure.” ~ Marc Smith

How is a Network Approach Different?

“There is a difference between volume and structure. Today, most tools focus on the volumes of things: followers, likes, retweets, etc. In contrast, a network approach has a focus on the structure that is created when people connect with one another. People often connect, but they do not do so in the same shape or structure – even if there are the same number of people.” ~ Marc Smith (emphasis mine)

Network Vocabulary

What are the core concepts and terms in networks?

  • Vertex = “the thing”
  • Edge = “the connection between two things”
  • Group = a collection of vertices
  • Centrality = a position of a vertex “in the middle of things”
  • Bridge = a vertex with an edge that connects to a vertex in a different group
  • Density = how interconnected everyone is to everyone
  • Centralization = how connected everyone is to just one or a few others (“hubs”)
