Dan Kennedy and Adam Gaffin are two of the smartest people on the topic of local online. Haven't heard 'em? Then ya don't know local. And if you haven't, good news: they're doing an hour of radio at 1 EST today, and you can listen live or download a podcast at Radio Boston. I'll be in the backchannel at radioboston.org and, Murphy willing, tweeting it live on Twitter, where I'm @lisawilliams.
