Addy is a startup that lets you embed your own customized turn-by-turn directions (Go about a mile, make a left at the pizza place with the green awning, my house is at the top of the hill, last house on the right) behind a custom URL.

For instance, if you were having people over to your home, an Addy could include details about nearby stores for food and drinks, a buzzer code, and parking instructions.

Good idea.
