I just finished reading the internet radio and social cataloging sections in training. Internet radio is a tool I have used before in non work settings. I know that we had a computer here during the holidays that was tuned into a internet radio site that was playing holiday music while we worked. Other that this I have never really done much with internet radio as I really haven't had a real interest in it. As far as social cataloging, that seems like a good way to share information, especially on recommended books and reasearch sources. I will have to take a closer look at that to see what it offers and what I can do with it.
