WOW!!!
I found a new neat presentation tool called webslides. Check it out here
There is a short you-tube video on the web page but basically you can make a slide show out of web pages bundle them together and annotate them. Then you can share your annotations with others or keep them private for you own viewing.
This seems like it is a tool that could be used in all kinds of interesting manners. I could imagine taking web quests to that next level by adding additional comments or requests to the web pages used in a web quest.
Webslides could also be extremely useful if a group wants to discuss and debate information that they are all reading over the internet, and the list goes on and on.
Give it a shot and see what you think.
