LukeW covered the launch of Yahoo! Maps Flash-based UI today. I was a bit surprised to see this done in Flash as nearly everything compelling that’s been released this year was based on AJAX. However Y! shows that there is still a place for Flash in this demo. Slick zooming with the scrollwheel and the first web-based map with the ability to take more than two address.
Also note the local events browser that Luke covers as well for a clue as to how a company can make their own mashups of various properties.
