The document then discusses functions of different social media sites and how online communities and cultures form through shared meanings and communication. It analyzes uses and gratifications of social media and how power dynamics play a role in online interactions.

10. Uses and Gratification
- Social media offers a range of potential uses

11. Online Culture and Power
- Social media communication happens within a cultural
context of values, ritual, and even chaos
- Some use social media in an effort to maintain existing
power
- Others use it to try to grab new power

13. CMC and Social Media
CMC = Computer- mediated communication
- It started with interest decades ago in discussion boards and email
- CMC did not offer communication that was as rich as face-to-face
communication
- “Flame war” = twitter fights
- CMC is a tool that may lead people with problems to take these into
online environment rather than, as is often assumed the negative effects
being caused by online usage

14. CMC and Social Media

15. DISCUSSION QUESTIONS
1. CMC has influenced the way we form relationships in the sense
that we have the capability to form relationships with people
across the country/globe within seconds. We have the ability to
communicate at any time of the day no matter where the other
person is without having to wait. It does make it hard because
even though the communication is more frequent - it doesn’t
mean we actually know the person the way we think we do.

16. DISCUSSION QUESTIONS
2. More of my media use consists of sharing things I find funny or interesting. I
don’t necessarily use it to maintain relationships. The Cmc relationships that I
have are weak in that sense. If anything the use of Facetime has helped my
relationships. Communication patterns based off of my social media involve
sharing videos/memes with friends and looking at pictures and images shared
through social media. I also use snapchat pretty often but only to send videos
of myself being silly. This would not be the best to use to influence future
online behavior because based off of my social media use, communication
through social media seems to be dying down in the sense of its purpose
being to maintain relationships. People will only share more videos and
images rather than build and maintain relationships.

17. DISCUSSION QUESTIONS
3. This is my favorite meme because it
is the most relatable thing ever. I do
this every single day while in the
shower. It transfers cultural
understanding because I think just
about anyone who listens to music in
the shower can relate.
