This needs to be mentioned: Yahoo has announced new features and a new look for Yahoo Maps. In particular, I’m paying attention to the inclusion of neighborhood footprints in two cities (New York and San Francisco) with more to come, and the “search by point of interest” feature. This is important from an SEO perspective because neighborhoods and landmarks are often a part of local searches. (Think “hotels near Space Needle” as an example.)

Greg Sterling writes a good overview at Search Engine Land. (Can I just start using the SEL acronym, instead?)
