For my own interests, public relations and media, there has been an ongoing Monday night discussion on Twitter called journchat (see http://journchat.info/ and seek "journchat" at http://search.twitter.com)/, in which PR people and journalists discuss their intertwined professions.
Last night, I stumbled on "editorchat" (find that also on Twitter search),with BusinessWeek editor John Byrne (http://twitter.com/johnabyrne) shared his thoughts on the state of his industry, sparking lots of side discussion and debate. I hope that is a series, I don’t know that much about it as of this writing.
That’s a small sample of what you might be missing. I am sure there are lots of other semi-organized discussions going on in the off-hours; or, you could start one.
