That poll is meaningless since what's considered a political bias is determined by your own political views (ie. "my opinion is neutral since it's obviously correct, others are biased") and will thus just reflect the bias of your audience.

It is such a weird space. Some of my highest rated comments have been pro-Trades Union, and it's regularly full of people decrying tech monopolies etc.
And then, on some stories, it completely shits the bed.

it's a bunch of different people with sometimes very different views, I don't think attributing an overall political stance to it is meaningful.

my impression is socially right wing, economically centrist, but with very high variance

And I'd add that a lot of HN's "politically neutral" is of the flavor where people with privilege not only ignore politics because it doesn't matter to them but actively suppress "political" discussions. Yielding in effect a strong status-quo, pro-privilege bias.

i found it depends, among other things, on the time of day. HN has a bunch of progressives on there, but they seem very tired for the most part. I have about a 2 in 3 chance of getting [flagged] [dead] on any post that either mentions i'm trans for useful context or is noticeably left leaning, whereas I see rational skeptic:tm: right leaning centrism ("US centrism") takes be assumed to be the default and correct take all the time.

I specifically don't have comments on my blog, but instead have links to my Mastodon profile and Codeberg account, from where you can easily find my email. I'm happy to discuss anything I've ever written about in those places. Posting links to my blog on HN feels like an end run around my intentions for how I wish to engage with readers. I very much wish it would go away.
