The focus of his talk is the concept of Twitter itself and how its uses have been adapted by its users (now numbering an estimated 4-5 million) since it was launched in March 2006.
Some of the more interesting factoids he mentions are that plants (yes, plants) can tweet for water, and even babies can tweet when still in the womb! Talk about digital natives...
He ends his talk on a hopeful note, saying, "When you give people more ways to share information, more good things happen."
To demonstrate the power of the tool, by end of talk over 50 tweets about the talk itself were already on Twitter, providing an instant feedback mechanism (for better or worse, as you'll see at the end).
I hope he's right about more good things happening when people share information. That's our hope in education, of course. I'm not so sure the US military shares the enthusiasm, according to this report in the Washington Post, which claims that this very 'information sharing' capability could lead to Twitter being used as a tool by terrorists! They give three examples of how this could occur, which I couldn't help but think was just giving the terrorists ideas!
The nature of web 2.0 tools makes them neutral in the hands of their users. Is this malevolent kind of use inevitable?
