Social media sites allow for two-way conversations and sharing media like blogs, wikis, Twitter, Facebook, Flickr, and YouTube. Common social media tools include RSS feeds, hashtags, and photo sharing. Social networks like Facebook, LinkedIn, and Ning are used to connect with people and share photos, plan events, and stay in touch. Podcasting and online video are used to share multimedia content and promote events. When using social media, one should post frequently, respond to others, listen, learn from mistakes, be helpful to others, and have fun.
