The document discusses the author's experience using various social media and collaboration tools for educational purposes. Diigo was found to be the most useful tool for bookmarking and tagging websites and PDFs to organize resources for teaching different subjects. The author had success using Pinterest, LinkedIn, and Twitter to connect with other educators and find new educational ideas. Creating videos on Animoto was also an engaging activity. The main challenge was difficulty following other educators on Diigo due to the author's student profile setting. Moodle courses were found to be easy to navigate but could be improved by displaying course dates on the main page.
