Listen to it. (Or at least read the summary) Then read David Carr's original article at the NY Times, "At Media Companies, a Nation of Serfs".
Yes, they're talking, in general, about non-fiction (sort of...I guess). Hell, just commenting on an article online is offering content for free. Some irony there, considering some of the comments on Carr's article. According to Carr, your Twitter feed and Facebook profile are forms of writing for free. Yikes... Facebook has learned how to cash in. Twitter isn't there. Yet.
Look--this isn't new. I occasionally listen to sports talk radio. I know, it might seem a little "out of character" for me, but it is entertaining. And you know what? The callers provide much of the content (and they are weirdos). No, it isn't a new phenomenon at all.
But is it scary? Yes, especially to anyone who wishes to write for money. Is there a corollary to fiction? Hell yes. I read a good deal of fiction online for free. Yes, many of the markets are well-paying (Apex*, Clarkesworld, Fantasy, etc.), but I'm not buying copies of Fantasy and Science Fiction or Asimov's when I'm spending my limited reading time with Redstone SF or Lightspeed online for free. I currently have subscriptions to Shimmer, Space & Time, and Necrotic Tissue. I try to spend a little money on small press every month (books, etc.), but the writing, I think, is on the virtual wall.
Will I stop blogging? No. Will I stop commenting on others' blogs, tweeting, or any of the other content-creating exercises? No. Am I going to throw an old-school Harlan Ellison rant about paying me? No.
And writing fiction? I'll quit when I'm dead. (but hopefully not from starvation)
*okay, so I did sign on for the Apex subscription, but I could read it for free.
