The most amusing bit is how clearly it comes across that the person who offers the commentary at the end doesn't write very well.

I noticed that as well. It was almost so obvious that I'm wondering if he wasn't doing it on purpose.

"Our hyperrich storytelling friend" couldn't have been written but on purpose... I hope.
Though his sense of humour seems rather weird.

"...the only bad writer is one who doesn't get paid"? Not in my world.

I enjoyed King's book, On Writing, a lot more than this piece.

Harsh, but true IMO. Stephen King might not be my favorite writer, but he certainly knows exactly how to be successful in the trade.
