IM Questions

Have you used any other IM programs before?
Were you surprised by anything?
How do you feel about IM as a mode of communication?

This was the first time I used this at work. Several of my coworkers and I sampled a group talk and it was very entertaining. I don't think I will use this as a main mode of communicating because you have to sit at the computer for to long. I don't mind phoning someone or shooting them an email instead,
