The Public Media 2007 conference in Boston looks to be well-attended (which it should be, because it's become the must-attend meeting in public broadcasting IMHO); alas, not counting yours truly due to a rib injury. Rob Paterson looks ahead to it in a post titled, Public Radio - IMA - A Tipping Point? Link: Robert Paterson's Weblog.
Doc Searls does the same (Forpodplay), linking to a Dave Winer podcast that previews remarks the latter will be giving at the conference. Link: The Doc Searls Weblog.
I'll be collecting and linking to whatever I can find coming out of the conference. --Dennis
