But whether or not YOU should find these articles intellectually gratifying is beside the point. We already have a feature for those kind of articles: don't upvote them. Flagging is not for those kind of stories. Again, if you find a discussion inappropriate, flag the comments in the discussion. Anyway, I don't think this discussion is going to be productive any more, so this will be my last comment.
I probably would not have flagged the perl/gnuplot one, I'll grant you that one.
Node.js articles are on topic, even if one or the other happens to be boring. So I would not flag them, even the most uninteresting ones.
