The New York Times, which recently started charging iPad readers $20 a month, has a lot of angry digital subscribers after an update broke the NYTimes for iPad application. The update was designed to make it easier for readers to subscribe to the Times through iTunes (irony!) but instead left readers unable to access any articles. Worse, the Times didn't bother to fix the app over the long weekend or reply to users who complained on Twitter. It's not the first time developers have broken an iPad application with a poorly constructed update, but reader complaints noted that the size of the New York Times and the high price it charges make this gaffe particularly galling. Angry users have driven the app's rating down to less than two out of five stars
