I'm doing a presentation on Web 2.0 Tools tomorrow and need examples of Diigo, Clipmarks, Panraven, and Comiqs being used in elementary, middle, and highschool classes. Please send links if possible. I already have excellent examples from the Web for wikis, tikatok, and voicethread. It's a 50-minute presentation so this is more like an introduction to Web 2.0 for most teachers at my school because we just got Smartboards. We also have virtual school when the need arises.
