The always pre-revenue what3words company has been buying up advertisement slots again, and there’s been some pretty unquestioning – might I say gushing – press coverage lately too.
I found this very interesting video which lists several of the serious weaknesses of the company and system.
A particularly big no-no for the Mapio Cymru team is the lack of open licensing of the data and software, mentioned in the video – and as a result the lack of peer review of the system.
The confusion inherent in converting from one language system to another is a cause for concern too.
