Ok, sorry. I've got no skin in the game either way. I do know it does work though. I live in the sticks, I've tried texting satellite images of our house with our house circled, precise grid co-ordinates, postcode and house number, detailed directions (left at pub, right at war memorial etc), But the only thing so far that seems absolutely fool proof is w3w.
In that scenario, here's what I'd do (Android/Google specific.)
Go to Google Maps
Long press on location
Click share
Choose messages (if you want to text) or emal, whatsapp etc
Choose your recipient and it will send a google maps hyperlink
Here's an example - just did it with Trafalgar Square
London
The recipient clicks the link and can get directions from wherever they are (W3W won't help with directions)
My reservation is that it seems to be a GREAT solution if you need to get some co-ordinates out of computer A
put them into a human short term memory for a bit, and then get that human to enter it into computer B. What I can't get past is that it will always be better to get the two computers to talk to each other. You can nearly always reformulate the communication chain to avoid the human brain bit.
The DNS analogy is very good. (But is gets flawed when you take it too far ... so I won't ... oh go on then: DNS enables a domain to be represented by lots of ever changing IPs. W3W is one to one)
I'm still unconvinced of the
need for such a DNS. Why put the information into short term memory in the first place?
But I think I'll leave it there. I've made my doubts clear.
