What makes you say this? Are all positive reviews a corporate sponsored promotion in your view?
Well, the article itself is not discussing the merits of Kindle Voyage so the comment looked out of place for me. And certainly marketing via internet comments is a thing, even on HackerNews. I think it's called "integrated" marketing, or whatever the current newspeak for that one is. Regardless my comment was mostly made tongue-in-cheek
Wat? Somebody's positive experience with an eBook reader is certainly on topic for an article discussing eBooks.
And two seconds looking their karma and other comments makes it fairly obvious the OP isn't an Amazon shill.
Sorry, not meant to be an Amazon shill, just pointing out that eBook readers are getting better. I thought it was on topic for an article about reading books on paper compared to screens -- not all screens are created equal. The Kindle doesn't have quiet the contrast of paper, but other than that, the print quality is comparable.
