To answer your question, Stack Overflow is for getting information, and this is for proving you have knowledge or skills.
The proof is through solving community-made problems, and discussion.
This is an accurate score that indicates whether someone is qualified with a skill or not, and we imagine people showing their Aptt scores on resumes, rather than needing a college degree.
The page we made was just to basically see if this is something people are interested in.
