Here's a great idea. The next time you are attending a meeting, you, along with your peers, can take notes that are saved on the web. Your group can edit the notes together and changes are instantly shown on everyone looking at the notes.
There's the ability to chat while taking notes and have an ongoing backchannel discussion regarding the event or presentation.
There's no sign-up or cost either, making it easy to begin to create your text.
Super idea for BYOT and BYOD activities!
