8. Beginning of Social Network

9. Enumeration Rapid growth
Countless users in the beginning (Early Adopters)
Low network connectedness
New members join more quickly than friendships can be established

10. 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

11. 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

12. 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

13. 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

14. Petri Net

15. Everyday Use of Established Social Network

16. 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

17. 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

18. 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

19. 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

20. 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
