I have just come across this interesting YouTube video created by Coventry University, regarding the future use of technology and the "culture of immediacy" or IE -(Immediate Everything). I found this link via Cristina Costa's Twitter tweet. Cristina is the creator of the fantastic Ning Digifolios and Personal Spaces workshop that I am currently attending online.
The video would be an excellent starting point for a class discussion about the future of the web. In particular, this quote from the video struck me- "In the future, online social networks will be like air". That is a powerful simile indeed.
