AS PAUL WALSH so eloquently demonstrated from Barcelona and beyond, interactive public broadcasting with mobile phone technology has tipped into a mainstream activity. Flat rate data charges make it affordable. High-speed 3G service or easy access to open wifi nodes makes it easy to push content directly to a global audience. But as Mark Comerford points out, "Good phones are not seen as a necessary journalistic tool by almost any of our news organizations. While we play catch up to yesterdays technology the new players are once again the public and they are just streaming ahead." I think that it's important to respect privacy when walking around with a streaming device but those sensitivities aren't always shared by the early adopters.
