I can read the `news` news in many places, and I do, but I like to come here for industry and niche technical topics.
Many I've spoken to share this sentiment and I hope this is of benefit to anyone wishing to focus more on what they are interested in.
You can block a source or keywords with the same rule:
news.ycombinator.com##table:not(.fatitem) tr > td.title:has-text(/{phrase1}|{phrase2}/):nth-ancestor(1)
e.g. a brief sample of sites that are not principally about technology and recur somewhat frequently (choose your own):
news.ycombinator.com##table:not(.fatitem) tr > td.title:has-text(/businessinsider.com|dailymail.co.uk|foxnews.com|theverge.com|cnn.com|reuters.com|zerohedge.com|insider.com|bloomberg.com|euronews.com|theguardian.com|wsj.com|ft.com|theconversation.com|thetimes.co.uk|bbc.co.uk|nytimes.com|newyorker.com|theatlantic.com/):nth-ancestor(1)
or simply a phrase:news.ycombinator.com##table:not(.fatitem) tr > td.title:has-text(/web3|crypto/):nth-ancestor(1)
This rule isn't perfect as it only removes the title line and keeps the number of comments, but it is definitely good enough and I am enjoying reading HN a great deal more.
You can add these to your Android phone too with Firefox and uBO.
