Guided Guider

So I like to travel, visit, and generally explore. However, reinventing the wheel everywhere you go gets old, and guide books are okay internationally, but not that useful domestically. Moreover, I want to go to my friends favorite dive bars, coffee shops, breakfast places, park benches, and so on. Rarely do they have the time or energy to remember all the places they would recommend. So here is the rub (idea): Create a map application that allows you to bookmark (either from the phone or at home) the exact location of places you love. For example, I would send people in DC to breakfast at Jimmy T's. But, I can't remember exactly where it is, and don't really like going through the direction giving. So I put up a little marker on Jimmy T's that says, great breakfast at a diner diner, not one of the many swanky, not that much fun, kinda too expensive places littered throughout the white parts of DC. And I put up a marker at Circle Current in VT (my favorite swimming hole in the world), and one at my favorite coffee shop, and one on top of Mt. Abe (one of my favorite hikes), etc. My friends all over the country do the same to our shared map, which is private to our group, and we get to see the places that our friends love the most without bothering them for directions. There are endless improvements and modifications that follow (color coded by person, type of place, seasonal recommendations etc). I know google maps can be shared, but the interface is poor and it isn't fun to use. Anyway - that's the idea.
