I love your article Melanie on the 5 tips for using Web 2.0 and I really love the suggestion of Voki! I am a huge fan of asking kids to get out of their comfort zone and I know a good way to do that is class presentations, but I do know some students may struggle with this for more than just being nervous. Some students with certain disabilities might not be able to fully present in front of the class and this Voki site was great for that! I actually was playing around with it and I hope it works, but copy this link below to see if you can view my message... it was fun!!! HAHA Thanks for sharing this article!
