What are your most common experiences with social media? Have you used Facebook to invite your friends to a big event, or used Twitter to post a link to a campaign you support? While these are more common, new capabilities of social media are only just being realized.
For example, social media will play a big role in the upcoming presidential campaigns and election. Social media has promoted Earth Hour, an environmentalist movement to reduce your electricity usage and become more aware of the planet. And now the latest: social media is employed by thousands of people in the United States who wish to avoid deportation.
