A good word for What3Words:
What3Words is an impressive tool. Your toothpick example blew me away. Easy to retain that kind of address than the standard coordinate systems out there. Not only for finding things, but also it can become a To Do or a reminder. A farmer might use it to have a list of specific parts of a field to focus on for a particular week.
Use:
So why not use What3Words to geotag in tiddler titles?
As per your example, this is what I might do:
2509-26–forces.deflection.ladder–350–Toothpicks
Initially, this would be the title of the tiddler so I could record the information quickly. Then I would take the parts and place them into their respective fields and values:
w3w: ///forces.deflection.ladder
cost: $3.50
brand: Between The Gums
stores: Fuji, Wallgreens
… and leave the title simple:
2509-26–Toothpicks
Simple tiddler title. Unlikely to find naming conflict there.
