> Their claimed solution when I read about this the last time was that similar words are designed to be very far off in order to make them obviously wrong, and showing similar addresses as a "did you mean" when you search for one. I don't buy their claims. If they cared about human-friendliness and recognized the possibility of errors, the proper response would be to add an error detection scheme like barcodes. The use cases of what3words are even more diminished by requiring an app to see what's wrong. > Also, they have country-specific word lists. I do think the needs for localization is properly recognized (of course, one can get better geocodes by eliminating the possibility of natural languages in advance). But the resulting system is bad: they breaks down after the translation. And also as a native Korean speaker the word list is strange enough to me ;)
