It's not a particularly good user experience to have a bunch of different unrelated products being discussed under the same article. It's a lot easier for me to just click 'next' and go to page 2 if I'm interested in reading more articles than it is to keep track of what everyone is talking about in a comment section with hundreds of posts and dozens of threads.
Or when Google announced the new chrome cast and music streaming device?
Both were at the top on their respective days and discussed ad nauseam in the comments.
It's not. I'm not sure why you're asking this.
Edit: we buried the "preview" stories, though. That's too much when there are already several actual launches on the front page.
It was not only extremely confusing, but it also effectively destroyed the discussion on topics like the Hololense that I was keen to see discussed.
