Wii are not playing PS3. New numbers showed that Nintendo's sprightly video game systems -- the Wii and the DS -- widened their sales lead in Japan over Sony's more expensive Playstation 3. Nintendo is now out-selling Sony by a 5-to-1 margin. People are playing so much Wii they're even getting injured.

But CL users looked to be pretty angry about the move.

Ask what Ask can do for you. Ask.com, the world's fourth-most-popular search engine, unveiled a site redesign that it claims yields better a better search experience than Google. The company also expanded its $100 million marketing campaign; the effort started with cryptic and uncouth anti-Google billboards ("The Unabomber hates the algorithm" -- huh?)
