Yes, Greg. Manny and Wilmer are in absolute charge there. Wouldn't have it any other way. But I also view it as a grad level course, in terms of your metaphor. In those instances, commentary and critical thought are crucial for the successful continuance of the learning process.
The best classes I have taken or have taught have been ones where there is alot of discussion and student-oriented facilitation by the teacher. The teacher sums things up, poses new problems to solve or new ideas to examine, but essentially allows the students to grapple with things. (Check out constructivism).
Any great scientist understands that his theories are going to be denied, tested, disclaimed, and attempted to be proved wrong. That's how science works. If his theories stand up to all of that, they come to be accepted. Differing views and opinions are the reason we understand as much as we do now. More later....gotta tuck my boys in.
Ok. Well. 3-year old needs a drink. Go figure.
So if we gather more opinions, read more, see more points of view, we will come to a greater understanding. Maybe even a deeper respect for what Manny and Wilmer do and say. And maybe a greater respect for some of our colleagues of lesser experience. I've read some pretty outstanding things by people other than Manny and Wilmer on their forums. Sometimes there's the odd mysterious guest...then hold onto your hats and get some good chips and dip 'cause it's gonna get interesting.
