Will they do the reading?

Without required weekly discussions, I am worried that folks won't read. And the readings are really critical to getting this stuff... I am making an effort to require annotations and citations with Culminating Projects, but that isn't necessarily an immediate application of the reading to something. Yet, I don't want to add back in required weekly discussions...I just think it is an overload. I wonder what will happen, and how the learners will react.
