These days it might be hard to remember that the Yahoo Maps API was ever second fiddle to the Google Maps API. These days, it barely picks up its fiddle. And in less than two weeks, Yahoo will lift its once-mighty mapping API above its head and bang the fiddle repeatedly into the stage like Pete Townshend. The remnants, barely held together with strings and the crumpled instrument neck, will then go in some dumpster in Sunnyvale. It's okay, after all, because Nokia's Ovi Maps API will be a fine replacement. It's only the nostalgic, like me, who'll have any problem with seeing the Yahoo name disappear.
