Interesting new directions-by-phone service with a "why didn't I think of that" phone number.
Downsides are the fact that it's voice recognition and uses MapQuest for the actual directions, but reviews are positive and it uses some familiar tricks and tenants based on this WSJ review:
"It's smart enough to ask you if you know how to get to the highway, thus saving you from reading directions you already know."
"Symbols help to shorten the messages, like using "L @ Maryland Ave. SW" to tell a user to turn left at Maryland Avenue Southwest."
"While the mobile versions of these services are improving, the user interface of a cellphone isn't ideal for inputting addresses and extracting directions. Even smart phones with larger screens and full keyboards can be hampered by slow Internet speeds."
