BusinessWeek article about the Yahoo! group that's producing new offerings such as Pipes. Subscription required for this one.
Now, Yahoo is trying to tap its inner startup. On Feb. 7 the company released Pipes, a service that allows Yahoo users to combine, or "mash up," data from various Web sites (mixing news feeds from Google (GOOG ) and Yahoo, for example). Even more ambitious is the initiative that gave birth to the idea. Pipes is the first product to come out of Brickhouse, a new division of Yahoo scheduled to launch officially around the beginning of March.
