podcasts
and 
social networks
. The growth of social networks has been documented by 
Boyd and Ellison (2007) who describe social networking sites as:
 Web‑ based services that allow individuals to (1) construct a public or semi‑ public profile 
within a bounded system, (2) articulate a list of other users with whom they share a con‑
nection, and (3) view and traverse their list of connections and those made by others 
within the system.
The interactive capabilities to post comments or other content and rate content are surpris-
ingly missing from this definition.
Podcasts
Individuals and 
organisations post online 
media (audio and video) 
which can be viewed in 
the appropriate players 
(including the iPod which 
first sparked the growth in 
this technique). The latest 
podcast updates can be 
automatically delivered by 
really simple syndication.
