My experiences twitter in class have been troubling to say the least. First one of my classmates blocked my account, so twitter decided to block me and then I couldn't access my account for the rest of the week. Also when we did the quiz in class for some reason my account was very slow to load, so I didn't get to see the posts people were making until 30 seconds or a minute after they posted them. Maybe that was just a product of being blocked, I don't know but it still made it difficult to keep up with the class. We used the tweetdeck during the quiz which I liked a lot because it only put the stuff on their that had to do with the class, if you haven't used it yet you should. In my previous experiences with twitter I have never used it as a learning tool or something to help other people learn with. It has always been used as just another social networking site.
