Beginning of Social Network

Enumeration Rapid growth Countless users in the beginning (Early

Adopters) Low network connectedness New members join more quickly than

friendships can be established

Propagation Period of ongoing growth in which both

membership and linkage increases Early adopters form links between

themselves and other users Users share multitudes of photos

Adaptation New users start out as power users Settle into their user class

Singletons Middle region Giant component

Stay at this level for the rest of their membership

Elimination Singletons contribute little to the social

network Their photos are only viewed by them Lack of contribution or all out abandonment

of the social network Can be considered to no longer be a part of

the social network Giant component and Middle region become

the driving force of the social network

Concentration Views, comments, faves, tags Top contributors Members of the Giant component Showcase the best the social network

has to offer All the photos that users decide to share

with the world

Petri Net

Everyday Use of Established Social Network

Enumeration Users have established profiles and set

of friendships Prepare photos for addition to social

network Create photo albums to store their

newly uploaded photos Possibly geotagged and/or commented

Propagation Sharing of photos/albums to friends in

network Makes links between users and friends

stronger May make albums public and share with

entire network Adds content to network

Adaptation Change in users and photos transparency Public vs. Private Making photos public adds more value to

the network as a whole Making photos private (only visible by

friends) limits the exposure along the network

Personal preference

Elimination Photos that are not viewed or shared Have no bearing on the network itself Contribute very little to the overall

user’s experience These photos will be lost among the

more popular albums

Concentration Similar to previous model concentration Focus is more on photos and network

content Network becomes concentrated on

popular photos/albums Popularity determined by

comments/faves/views
