Why so strange. There is a lot of information out there from multiple sources - both written and verbal. Some we all have access to, some we don't. Personally I'll take second and even third hand information and evaluate it accordingly. Historians do that all the time.
I think the poll question is more along the lines of what you consider a good teacher and did Ueshiba M. fit the bill.
