The article definitely could be improved. I kind of guessed what the author to say at the beginning, but it was not really clear until much later. Had the author shown a side-by-side comparison at the beginning, it would have helped.

I think that was the intent, but my point was that even a side-by-side isn't worth much to someone truly clueless who doesn't know what to look for.

If a picture is worth a thousand words, it's extremely difficult for me to determine which of those thousand words are applicable, and without guidance introduces a ton of noise.
