I have some concerns about this kind of technologies. I like technology, am not a Luddite but we should be cautious and use it …….. not be used by it. Who’ll take control of all the data gathered ? How it could be used ? What information do we really need ? Will be really possible to switch off a Waveface or something similar ? Could be a way to trace all of us ….. maybe one day not so far ? …….. or we are already traced ? Am reading Little Brother by Cory Doctorow and I feel a little bit worried using Buzz on my mobile phone …..
