Social networking
'In social networking communities…an initial set of founders sends out messages inviting members of their own personal networks to join the site. New members repeat the process, growing the total number of members and links in the network.'1
Examples of popular social networking sites include Facebook, MySpace, Bebo and Twitter.
Sites develop this idea further by allowing users to build up profiles with photos, applications, join groups and view friends profiles and updates.
