This seems to be a common thing with aggregators in general. As someone who's seen their work posted to Reddit and other sites (or has posted it there themselves), the aggregator topics seem to get a lot more views and comments than the source article does. I think in many cases, the system comes down to "upvote the topic and comment if I agree with the premise (or what seems to be it), or downvote the article and comment if I disagree with the premise (or what I think it seems to be)"
