From Lifehacker:

Yahoo!’s released a new version of their mapping tool with a Google-like drag and drop interface and the ability to get directions to and from several points on one map.

Unlike Google, the Yahoo!’s product is Flash-based, and includes a magnifying glass lens-like controller at the top right you can use to zoom or focus on locations. A Live Traffic checkbox overlays construction sites and traffic snags right on the map. Yahoo! Local search is built right in with business names and addresses available as pop-up bubbles at locations. Map developers will be happy to know that a rich mapping API is readily available, too.
