The solution to low karma — if, indeed, you care about such things, is to make productive comments. Most of us have heard all of the simple one-liner thoughts before, we want something that might be insightful and novel. And politics-adjacent threads like these are not the place to earn karma, because lots of people will always disagree. But it’s an excellent place to lose karma.
A lot of us go to places like HN, Ars, TechCrunch because they’re something of a refuge from intractable boring political dilemmas. Solving technical problems, old war stories, discussing software and language features, sharing historical curiosities: those sorts of things earn karma.
That’s not to say politics is unwelcome here, but these threads make it so much easier to accidentally offend another. I’m highly involved in a US political party, but I rarely bring it up here because it’s unproductive. That said, go vote!
