That was true in an age where there were only a few channels or methods of dissemination, each of limited bandwidth so that some curation has to happen. I'm not so sure that's quite as true now, where there's essentially no need to curate. We've seen several channels/modes of distribution overwhelmed with spam, ads and extreme content, Usenet one of them. At least some of the time spam and extreme context have to be suppressed.
