Conde Nast is making another foray into online technology with the local launch of highbrow U.S. tech Web site Ars Technica. This is Conde Nast Britain's first launch since "Wired," but the publisher insists that the two Web sites are quite different. "Wired" is all about "the future of technology," while Ars Technica is "the most trusted source of insights into what is at stake today in the world of technology." It is a hit in the U.S. last month, receiving 75 million page views and 12 million unique visitors. The UK accounts for 12% of its traffic.
