How would that not push people to agree with each other on everything, which would essentially turn debates into echo chambers, or push people to be as wildly oppositional as they could be, which would eventually end up as virtual screaming matches? Perhaps I’m not following, but that boils down to, say, Televangelist vs Shock Jock in the simplest of comparisons.
Also, does the “rate my professor” thing ever actually accomplish anything and, if so, what?
I’m genuinely not seeing the benefits. Help me understand what you’re suggesting.
