I'm currently in an online chat with my CSU Fresno CI 227 class "Current Issues and Trends in Educational Technology". We are using Blackboard and the chat feature to discuss a few topics in real time online. It's quite interesting in good, bad, funny and annoying ways.
That's technology for you. I like to remember that using Twitter, chats room, educational technologies in general must be very similar to the experiences that the first automobile drivers had, phone users and cowboys learning to hide the wild stallions. A LOT of pain for a little fun.
