Also, a lot of those media and BigCo stories really are of interest to the community. We try to dampen the stuff that's repetitive, and most of those sites are downweighted by default, but HN would not get better if they were excluded. It's all just more complicated than it seems like it might be.
What ultimately matters is how interesting a story is, not what site it comes from. I'm suspicious of encoding proxies for that, because it would be easy to end up optimizing for the wrong things. https://hn.algolia.com/?dateRange=all&page=0&prefix=true&sor...
Rather I think obscure sites should get more opportunities to be organically upvoted on (and if they don't get voted up, then fine) and not just fall off /new after a few hours only to be seen by a few people. The BigCo stuff naturally gets posted often several (different) links from different people, whereas obscure stuff is only posted by a single person once. So this is about evening the odds.
I'd rather have eclectic ideas and projects from HN users not be overlooked (thus encouraging more of such content), and am less worried about GAFAM announcements, CNBC/Axios/BBC news, or things already popular on Twitter/Reddit.
Would this be a doable change to try?
