Further proof that print-based communication are on their way out? At the offices of The New York Times, Twitter usage has become so rampant that it brought down the Gray Lady’s computer system. Twitterers in the newsroom apparently use the application TweetDeck, which allows users to access Twitter but isn’t actually made by the start-up site. “It…takes a serious bite out of the performance of many computers, particularly PCs,” an internal memo read. “We recommend against installing it or using it on Times computers.” NYT stopped short of actually discouraging the use of Twitter, promising to look for an alternative that is “both safe and easy to use, for both casual and power users.” Admitting you have a problem is the first and hardest step.
