This blog post outlines types of social media that can be used in the classroom. These include Twitter, blogs, Flickr, Skype, and Pinterest, and Tumbl.
Social media may have started out as a fun way to connect with friends, but it has evolved to become a powerful tool for education and business. Sites such as Facebook and Twitter and tools such as Skype are connecting students to learning opportunities in new and exciting ways.
I like this site as it offers innovate ideas for bringing social media into classrooms. It also categorizes the suggesions by levels - K-12 and college. It also gives suggestions for students' use and for teachers' use.
