Yourgmap.com - Share multiple locations with friends via Google Maps

This is another reason why I've sworn off Mapquest for good. Yourgmap.com offers a great tool for Google Maps that hits my nerdy, techno-loving, can't-find-my-way-anywhere g-spot. Some things I love about this:

1. If you click on the arrows, the address pops up alongside any comments you make (I've put down contact name and meeting time).
2. You can either share the map via an email or embed it into your website (as I have done here).
3. I have already thought up several ways to use this:
- Location scouting / Site visits with clients - we're definitely going to use this for the upcoming Pink Cloud photo shoot for the fabulous modern dancer / choreographer Michelle King!
- Party Map for the designated driver of my drinking pals!
- Map of favorite restaurants and hotspots to share with out-of-town guests.

Anything else I'm missing?
