The new (beta) "Yahoo! Maps":http://maps.yahoo.com/beta is very slick!

* Nifty flash interface
* Live traffic (have to wait to see how good it is)
* Search along a route (e.g. gas statios on my way to the airport)
* Reverse business lookup
* many more, see "SiliconBeat":http://www.siliconbeat.com/entries/2005/11/02/yahoo_maps_a_flashy_interf...

I've been enjoying this Yahoo revolution of late. Well done.
