The word “podcasting” is combining the words “broadcasting” and “iPod.” The most popular format of a podcast is MP3. When I first heard of podcasting I didn’t understand what made it different from simply searching and then downloading a music file and listening. One of the most common podcast subscribing tools is iTunes.
I liked the concept of YouTube where you can upload your movies, pictures or any crazy thing. The downside is that life is no longer private. Ofcourse, Gen Y love it. Their popularity is judged by how many hits to their posting. YouTube is very helpful for product guides you could say it is a virtual product launch
I have visited Hennepin County Library facebook. It is a good site that allows people to chat with librarian, search catalog, register as a fan, and also post something on "wall". I am conservative in having such networking.
