I used readability on this link. It actually dropped the 'Epilogue' on this one which left me scratching my head for a couple seconds before I backed out. But readability is incredibly handy on almost every ugly/noisy content page, it's one of the few tools I use every day. I didn't know Safari had a "Reader" button (I usually stick to FF/Chrome), out of curiosity do you know who implemented the idea first?
