Poifriends
POIfriend is the point of interest community that connects people and the places important to them. POIfriend is a powerful, fun and easy-to-use website that lets you find, create, comment, rate, share, and use POI (Point of Interest) information with GPS or maps. It is 100% FREE for users and detailed personal information is not mandatory.
If you own a GPS-enabled device, you already know the value it provides in getting you places you want to go – most often by voice-driven turn-by-turn directions. However, most users agree that many standard POIs pre-loaded on your GPS device are either out-of-date, incorrect, missing, and not personally relevant.
