I know that I am way behind the eight ball on this one, and I have a tendency to exaggerate things, but... This is the best 2.0 tool for comprehensible input classrooms. I only say that because I can't think of one that I like better. This is EASY for teachers and easy for students. It takes less than a minute to "Textivate" a text, and there are twenty-seven different activities that your students can complete while interacting with the text and getting reps and reps and reps and reps!
