The Chris Lydon radio show, Open Source, did a show on hyper-localism that featured Ed Remsen, mayor of Montclaire NJ, who isn't above commenting on posts on to Baristaville. As Brendan Greeley, of Radio Open Source, points out, Remsen isn't a born-on-the-Net hip guy. But he sure seems to get that the Net is an unowned conversation, and that his constituents are talking.
