"But I guess that's also the typical dynamics of comments, people jumping quickly on first posts, imposing such pace, and then it quickly dies out."
Actually, this is probably a consequence of the voting system used on OSNews, which artificially restricts voting later in the discussion. Unless one abstains from voting (and posting) at the beginning of the discussion, they'll loose their ability to vote on posts later in the discussion when only those with duplicate accounts or who didn't post can vote. I prefer a strait forward voting system, because the current one can't be considered representative.
