In the OP's defense, I think the article is a good basic overview of how to find, enter and how the general flow of things work at a show. I don't think she intended for it to be a step-by-step guide on how to show like a pro.
Yes, starting with an excellent mentor is ideal but the reality of the matter is there are increasingly fewer of those individuals around. Additionally, getting the privilege to own and show a quality specimen of the breed is an honor itself--one that is not given easily. For someone starting out it may take that "mistake" purchase and the demonstration of that individuals passion for the breed to prove that they are trustworthy with a quality dog from a quality breeder.
For the vast majority of those interested in showing--you just need to get out there and do it and learn as you go. Even if you have a mentor you cant undermine the value of lessons from the school of hard knocks--those tend to stick around the longest!
On the bright side, if the OP's article gets a few newbies in the ring we could a) use new blood in the breed and b) use the additional entries
