there's a new and effective way to give very specific directions to where you are, so someone can find you... regardless of where you are, in those typical circumstances where finding someone in a crowd is necessary, like, at a big outdoor event with no landmarks, such as concerts, Burning Man, race tracks, etc, or when you need a taxi to find you

here are some examples, and business associates above... because it's a lot easier to find a specific place, with a 10 foot square area location.

Postal zip codes are vague, street address searches drop pins in the center of buildings and many places, like entrances, parks and beaches don’t have an address. With what3words, you can find or share any precise 3m square in the world using just three words. 

Like Burning Man for example

also there are obvious issues with street address names, because the English language and lazy govt workers all combine to result in problems caused by using the words Avenue, Street, Boulevard, Court, etc... so, it makes SENSE that using a grid system, that has a SIMPLE method that is easy to remember, and communicate, to designate a simple place.  As someone that was using GPS coordinates in latitude and longitude, as a professional Navy quartermaster navigations type, I can tell you that it's just overly complicated to use lat and long to achieve a precise location on the planet... you need charts or maps that ALSO use lat and long. 

What3Words doesn't. And, telling someone 3 words is a lot easier for them to hear, understand, and not forget or mistake, when you want them to know how to find a specific location. 

I like it.

I'm digging it, and if you were to want your friends to find you on a beach, or at a car show like GNRS or SEMA, I think you'd find it's a good idea too. Plus it has a free app.
