Yahoo! Maps +

Yahoo! answers Google Maps with their own updated version – very similar to Google’s, with the ability to drag and zoom, and it’s very fast.
Yahoo is also offering an API so that people can integrate other data with the map. One example of this is, which plots upcoming shows from (a recent Yahoo! acquisition) onto Yahoo! maps. The result is pretty cool, but – as the name suggests – shows are more about when than where, which is why is organized into metros rather than cities (which also makes it ridiculous that people have created a Cambridge metro when there’s already a perfectly good Boston one).
