Stephen Fry on Language

I like Galapagos.

Stephen Fry on fucking swearing.

His linguistics radio show is wonderful as well. It's called Fry's English Delight.

Fry's position in the OP's link is that of, as far as I've seen so far, every accomplished linguist. The only time language really needs to be repaired is when it's difficult to understand (or when written to a specific audience that will dislike the way it's used.)
