Monty Mullig, the head of Web technologies at Time Warner's Turner division, which runs CNN and TBS, among others. Despite CNN's efforts to burnish Mullig's profile by featuring him as a talking head, touting CNN's ability to serve up millions of pageviews in crises like the contested 2000 presidential election and 9/11, you've likely never heard of him. But nonetheless, his departure now is instructive. Turner, you see, is rumored to be planning layoffs in Mullig's department. It may seem odd that Turner, whose CNN.com is a runaway success in online news, would be plotting cuts as everyone else is scrambling to staff up with Web developers. But Mullig, and his long, prolific website-building tenure, may have a lot to do with that.
