Ask HN: I miss old days of blogging without promotions

I miss days when people were writing articles to share what they have learned, people are still doing it, but signal to noise ratio increased so much that it feels like most articles are to promote something, either promote their product, or promote their personal brand or just get more traffic to their website to sell ads.

What's even worse, a lot of those articles are generated by AI, I just dont want to spend even 15 seconds to read it.

Problem is, it is also difficult to detect if it is written by AI or not.

Where are the genuine knowledge sharing, human written blogs?
