If you don't follow this blog religiously but do care about evolving journalism issues and want to play catch-up, you might wish to check out News 2.0, a two-part special by CBC contributor Ira Basen that finished today on CBC Radio's The Sunday Edition (part one ran on June 21).
Maybe the audio for part two will be attached in the near future. Maybe not.
In any event, the last 15 to 20 minutes of part two are probably the meat of the whole matter. The rest is just background and setup -- however, if you aren't fully conversant with this topic, take the time to listen to both parts.
The News 2.0 web page has links and transcripts. The article itself is overly compressive and thus underly informative. I would disagree with some of the broad-brush strokes used to sketch the issues.
Interestingly, I do way more stuff on News 2.0-type issues than J-Source, but that website (link at right) rated a link from Basen and I didn't. I'm crushed! :)
