So.. What do you use? I use Twitter and Edmodo mainly. I can connect to teachers and educators all over the world. I can ask questions about something I am unsure about and BOOM !! I have an answer. Edmodo has subject and topic groups and a search bar that shows posts about whatever I have entered. Twitter has hashtags #??? that I can search and find relevant tweets on any given subject. Another good one I have discovered is Google +. I can add specific users (educators) to a specific circle I create and follow them and what they post. I LIKE being able to learn what I know I need and that I am Interested in. Let me know what you use and why.
