I'd guess the rationale for comments would be implicit before then. e.g. it's not strange to see that there's a chat alongside livestreams on Twitch, or a comment section beneath YouTube videos. There's a natural community of people interested in the content enough to comment. - I'd guess the difference here is that newspapers get significantly more traffic from social media. I'd also think it comes from a positive vision of technology. The internet as a means of "making the world more connected". Empower people to communicate in ways which weren't possible before. - Turns out this wasn't as positive as expected.
