I came across this website and just found it fascinating that it exists and that people have taken the time to create this kind of data.
There are all sorts of categories there, the digital one probably of most relevance to us software testers, however, other human ones could be interesting - https://www.dimensions.guide/browse/digital
Mostly highlighting it here as a potential research tool when doing testing. If you have ideas for a specific testing use it would be interesting to here them!
