I played with Jing and signed up for it. I can see how I could use it to show a home page of a website I was interested in sharing that show all the different tabs etc. they use. I really liked the Good Reads because there were some books I wanted to flag for future use and to see what others are reading that I could get into. I don't have a great deal of time to do this since I don't have a home computer so it really limits the amount of access time I have to play on these sites. I'm glad I know they are there anyway.
