But this is rather interesting. I am not sure this article deserved to be flagged. It's an opinion piece, so one can't expect too rigorous source vetting. That said, the reference links weren't particularly shabby.
And it's political, which goes against the HN guidelines. However: it does make couple of very interesting points.
The first one: that partisan media is more insulated than before. That's certainly a viewpoint that carries weight and has been discussed, in various forms, on HN for quite some time.
And the second one? That in the current political climate there is no more room for moderate and reasonable discussion. You either broadcast a polarised and incendiary view or get no visibility nor acknowledgment - but when you do submit to the attention economy, you get flooded and drowned out by the professional wound-ups.[ß]

[ß]: Modern Finnish has a term which I don't know how to translate properly: "ammattinärkästyjä". It would fit really well here.
