Honestly, I don't really know if it matters who you believe. Think the pastebin person is right and this was going to be pretty shitty? Think the vague PR indicates that it was really going to be this awesome thing? Ultimately, who gives a shit? They scrapped it. Maybe they scrapped it because it was worthless shit. Maybe they scrapped it because it was too awesome and publishers were never going to go for it. Whether it was a good feature or not, my working assumption is simply that it was half-baked nonsense they were making up as they went along, and they never did precisely nail down how it was really going to work.
