As I systematically revisit Jane Hart’s Top 100 Learning Tools List, I must confess that (like Adam Grant) I continue to discover new ways to maximize Twitter’s usefulness for me as a learning tool. Though I have no interest in becoming a Twitter Ninja:), I am delighted by the capabilities, for example, of creating lists of experts who regularly stream invaluable and current information on topics important to me (right now those topics are technology learning tools and global education).
