Everyone has seen the links to smart commentary on the Amazon vs. Macmillan skirmish from Scalzi and Toby Buckell, et. al. I'm sure, but I wanted to put a pointer to Caleb Crain's "Clash of the Titans" post, which is exceedingly worth your time:
Newspapers have no one to blame but themselves for having taught the public that they have a right to read newspapers online for free. Publishers, on the other hand, have woken up to the unpleasant discovery that the value of their work is being cheapened in the public mind by a third party: Amazon.
Seriously, if you're interested in this stuff, go read the whole post. (via Laura Miller on twitter.)
Updated: Also read Scott's post on the matters at hand.
