OK, months of work are now public: Metroblogging is officially live! That’s the project Jason and I have been working on so secretly. The first cities we’ve launched are New York City, Chicago, and San Francisco. We’ve got a kick ass group of bloggers involved, and I really can’t express how excited I am about all this. We’re working on more cities too, check out metroblogging.com for details or to apply or whatever.
