Twitter goes Geo a number of reports lately about the fact that the main site number of twitter apps will allow for geotagging of tweets. Interesting stuff - but how happy would you be to have your tweets tagged? Recently we interviewed a young Colombian who spoke about how Tweets in Colombia had been used to trace people and their behaviours and ultimately lead to kidnappings. Having seen Biz Stone speak recently, i like his "Quiet American" (check out the book and not the film) style, but his blind optimism of the power of Twitter to be a force for good rather contradicts some fundamentals of human behaviour.
