This is all new to me! I can see how a teacher could use alot of these websites for a classroom. Not sure if it is something the will work for the office. I liked Slacker of all the music sites because of its selections and ease of use. Apps didn't impress me although creating a voki was fun. I have to fiqure out how to put it on Google account. Diigo was more useful because you could highlight and bookmark.
I am use to either more hands on instruction or more detailed directions. I am finding this a little frustrating.
