This is why American cue sports are so far behind the rest of the world, IMO. In the rest of the world there are instructors and academies that teach and train players and they rejoice when players get better. Here there has been a culture where no one wants to tell anyone anything because they might end up losing a bet. And sadly it leaked into the 3C world.
Fortunately, some of the foreign materials are becoming more available. PLUS we get to see them do it via video. I remember the comment in one of Byrnes' books about the invasion of the Europeans in 1966. It was the first time Americans saw what post-Hoppe state of the art world class 3C was. Byrnes commented that Danny McGoorty, an old time American 3C player said, after seeing a shot by Ceulemans, that he wanted to chop Ceulmans' cue ball in half because there had to be something inside it for it to do the things Ceulmans got it to do.
Byrnes' book, when it came out in the 70s was a revelation. The only book I had ever seen on pool before was the little Mosconi book. I bought the book for the pool and it got me hooked on the billiards. Now there is tons of stuff available, but it was a desert there for a long long time.
OTOH, yelling at and scolding people is probably not going to bring out more or better answers. I'm grateful for whatever I get and I am fairly aggressive about searching out things.
