The Times joins 19 other papers, including the NYT, WSJ and Boston Globe, now available on Amazon's portable electronic gizmo that receives and displays books, blogs, magazines and newspapers. Thing is, accessing the Times via Kindle will cost you $9.99 a month (other papers charge too). Why on earth anyone would pay for material that can be accessed for free on the Internet is a head scratcher, but it's also a reminder of how once upon a time most newspapers and magazines passed up the subscription-based online model - perhaps the dumbest business decision ever made. Here's the Times post on the Kindle announcement.
