I don't think the point was that if, as beginner, you don't get hands-on time with the instructor every class then he is a bad teacher. Keep in mind that this post was written for a forum focusing mostly on Chinese arts based on solo forms. The nature of aikido is that you will work with other students for most of the class, so for beginners the opportunity to work with senior students who are much more skilled and perhaps even instructor-level themselves might be enough at first. At a certain point, though, direct hands-on access to the teacher becomes essential. I think the original post was addressing the larger issue of whether a teacher takes an active and ongoing role in each student's development via regular hands-on contact, not whether a teacher touches hands with one particular student during one particular class.
I thought so too, but it wasn't very clear, hence my post
