I always wondered if they were actually used by anyone then I saw their recent advertising and it seems to focus on emergency services and finding places in large fields I created a project using an alternative method using gifs for directions: http://gif.direct http://gif.direct which I personally think is more useful (if less refined!)

They are dangerous for emergency services, here is a case where W3W showed a location many miles away: https://twitter.com/isleofmandan/status/1386455377949122561 https://twitter.com/isleofmandan/status/1386455377949122561 Someone have also compiled a list of pairs that only differs by one letter, like these two: instants.lightening.precedents instants.lightning.precedents You can see the whole map here: https://twitter.com/cybergibbons/status/1385891425108250626 https://twitter.com/cybergibbons/status/1385891425108250626 I wish they would just use "pluscodes" instead, the algorithm is opensource and doesn't depend on a specific dictionary: https://en.wikipedia.org/wiki/Open_Location_Code https://en.wikipedia.org/wiki/Open_Location_Code

  You also need to distinguish between the contexts where you need addresses versus coordinates. Lat-longs, plus codes, and word-encoding schemes are all coordinates -- they identify a point or area on the globe. Addresses are last-mile navigational instructions. "Apt D, 123 Main St" allows anyone with local knowledge to navigate efficiently to the location indicated: first they drive to Main Street, then they proceed along the ~monotonically numbered parcels to 123, then continue to the apartment labeled "D". The advantage of coordinates is that they don't require local knowledge and can identify arbitrary points; the advantage of addresses is that they encode instructions for land navigation that takes into account which parts of the land are passable.

  Sheesh, lightening and lightning? Not to mention, "instants" when "instance" is also a valid word.

What is wrong with classical coordinates for emergencies? Like 42 degrees north, 13 minutes and 4.5 seconds?

  I know of one rescue that didn't go smoothly because there was confusion between degrees, minutes, seconds and decimal degrees.

    You could just read off a fractional N-W GPS coordinate like an average person. Every smartphone comes with a GPS app these days.

  Assuming you're reading these values off a device, most can display them in various different formats. It's pretty confusing and converting them isn't easy either.

    Yes, but does a system which uses singular and plural of words as a distinguishing feature really help here. (not saying that there couldnt be a better system based on words)

  It's easier to get confused. And there's still ambiguity. A few months back I was fighting my phone over this--typing degrees/minutes/seconds into Google on a phone isn't easy. I ended up using the calculator to convert it to degrees with fractions. Finding the spot along the road was a pain.
