GOTO is a live map showing where you and everyone else is. Use it to figure out a mutually convenient spot to host a meet-up or just watch to see if your friends are on the way.

Accept the geolocation request and you'll get a pin on the map. If you're using a mobile with GPS, then your position will update as you move. Don't worry, it's opt-in. Your browser will only update your positon while you're looking at the page.

If you've got a gravatar, then add your email address and you'll get a better pin. You're email isn't shared or stored, so go for it.
