When I started the quixotic journey to create a taxonomy of all human knowledge the most common (and well meaning) questions people asked me were: Why? What’s the point (you know Wikipedia exists right)? And the more obvious: Are you bonkers?
But I started because a taxonomy of knowledge primarily designed as a teaching resource ceased to exist. So, yeah.
