In fact why not disable all comments? Is the tutorial section supposed to be a discussion area or simply a place to find information? If a user has questions, then why can't he post them on the questions board?

This of course would probably require updating of the tutorials and I don't know if people would like doing that especially if the author disappears.

Another reason to disable the anon monk is simply a "gift" to the authors. If the author is willing to publish work that means he is ready for good or bad comments. If you are going to take potshots, then you shouldn't hide behind the anonmonk.

Tye said Meditations should be the area for the drafts and comments. That sounds reasonable.

I would ask why not make use of the voting booth to handle if something should be added to the tutorials?

I could see that causing discussions over the tutorial.
