Well-taught classes (and I took enough good and bad English classes to recognize the distinction) are completely irreplaceable by Google or MOOCs. They focus overwhelmingly on the art of discourse: sure, there are papers and exams but the soul of the class is in the daily lecture; everyone comes in with X, Y, and Z read and you discuss it, growing and pruning theories and interpretations of literature as one would an oddly looking tree. A good professor wants to teach you that Frankenstein is an allegory for the Industrial Revolution, or the creation of Man; a great professor knows the conversation that Shelley had with Chaucer and Milton and everyone in between -- and knows how to help their students figure out everything themselves, with just enough help along the way.
A good English course only needs a semester to teach you how to make a point, argue it, research it, defend it against a multitude of competing and contradicting points, and ultimately handle the reality that the point has been made many times before by people much smarter than you.
(This experience is magical, and something that really can't happen in a room with more than forty people, let alone a web app with hundreds.)
You develop along the way a finely honed level of communication (I had a fellow CS grad once suggest to me that 100-level English classes were about punctuation and grammar, and it made me inappropriately angry); you learn how to approach questions with no answer and conversations with no real goal, how to talk with peers, mentors, and people who died hundreds of years ago. You learn a tremendous amount about yourself and others through the lens of literature, honed tightly by a great professor and a greater book, because the way you approach any experience is of course colored by everything about you.
I switched out of the English department my sophomore year to pursue Computer Science, but British Literature II was the most valuable class I've ever taken.
