Description: Social Media and Mark Zuckerberg

In class recently, we have discussed what social media is, we have experimented with comment threads and posting, and we have learned about Mark Zuckerberg.  Inquiring minds would like to know: What does "Social Media" mean to you?
In your post, please include a link to an website or an image that has something to do with social media.  This will require you to perform brief Internet research.
