In my view community set DL is much more important that an author's
personal opinion. Firstly, it is one of feedbacks, which make community
to be real community. Secondly, it is just functional for all top
level UMOs: Courses, Dialogs of Texts and Through Problems,
because people need to compare them and opinion of others is essential
here. Remember, UU is kind of market place, where people shop around
for suitable learning materials and processes , they do need advice
of peers and professionals. Some community set marks (not only DL,
but some others too, like effectiveness, boredom, correspondence to
specific educational system, uniqueness, you name it) will make it much
easier. To sum up: community set DL is absolutely necessary.
