The Flash version of Yahoo Maps replaced the old-school version at maps.yahoo.com and got out of beta. Unlike Google Maps, the new Yahoo Maps lets you have "multi-point routing", so you can define a path using more than just two points and get directions.
Yahoo Maps added street-level coverage for Europe for most capitals and other cities, but the coverage is inferior to Google Maps. Yahoo continues to have a distinct local search engine, so you can't search for businesses on Yahoo Maps. But you can find unrelated animated ads, though.
