Intermediate Directedness
• Directedness is a really a continuum
• Many social media fall in between
– Facebook friends
– Twitter followers
– Google+ circles
• Partial knowledge of audience
– Meetings and public speaking forms also have some of
these characteristics
– These traditional forms tend to be same time,
ephemeral media
Ephemeral Media -> Archived Media
• Trend for ephemeral
on-line forms to
become archived
• People’s perception is
not necessarily
connected to what
really happens
• Why does this matter?
– When people are being recorded (archived), they
communicate differently
Blogs and Microblogs
• Are often for opinions,
reports on activity, humor
• Personally authored
• Although can become linked
– Microblogs can become
discussions
– And links between blogs can
become claim/counterclaim
structures
Why do people blog/microblog?
• Updating others of
activities
• Influencing others
• Thinking through
writing
• Release of
emotional tension
(catharsis)

authored resources

objective content

– Fan / player sites
• Include facilities for
collaboration
– Talk pages
