Collaboration is bad?

Trimbur's article critsizes collaborative learning. He notes that group think/talk supresses individualistic creations and conditions learners to conform. I think this is a very good point. Especially in the compositional field, individual thoughts and opinions are essential; stylystically- how would things be if everyone was writing about the same kinds of things, in the same kind of way? He seems to be suggesting that collaborative learning and group think debases subjectivity. Maybe not to the extent of internalized thought, but moreover, in a way that facilitates almost a 'hive' like thinking.
I have to say, this is one of the more interesting articles I've read. I think its important for academia and theorists alike to sometimes go against the grain, raising new issues and questions for others to consider. I wouldn't go as far to say that Trimbur is exactly right as his notions are more extreme predicitions than what would probably be realistic happenings. First of all, so much of the way we learn is through experience and the happenings of everyday life. This type of vivid experience is sheer fact and certainly individualistic. I think that if all learning was in fact collaborative, everything about our world around us would change. Culture would have to be collectivist in nature, and law would most likely be a product of a socialist society.
