I too have an (private) RSS "laboratory" project!
It isn't the elegant machinery you describe here as I'm quite unfamiliar with the technique you describe.
If I'm actively using it the feed list grows to about 35-40 000 at which point I find as many new feeds as I lose old ones.
I maintain a dozen categories of badwords, if any of those are in the headline it will be removed.
With many subscriptions things look quite different, higher frequency publishers start dominating the top of the newest list. The faster they publish the higher the standards I hold them to.
What is quite amazing is that some really terrible news websites use long titles that are highly descriptive. I have a good few of those, they get to stay around because the badword filter purges so much I hardly ever see them. For every 2000 bad ones business insider has a great article. It's a terrible website but their use of descriptive words in article titles is the best in the world.
The key insight imho is that the internet is much more of an echo chamber than people think.
As soon as you get rid of Musk and a few hundred other people, a few hundred companies, a dozen countries and a few thousand other topics you are left with a world of infinite other subjects. People are writing about stuff no one else ever thought of.
If everyone in the world is reading and writing about FOO it is absolutely amazing to get rid of FOO. There is no such thing as an important football match. (joking sorry)
Everyone is praising normality but you should really wonder who creates these norms. If they are good of bad people is besides the point. Musk says 1 something interesting per day I'm sure. For every 100 000 topics inserted into the collective we chose 1 then, by the tens of millions, we talk about it. Every day is Musk day.
It doesn't matter how hard you resist participating, eventually you will learn that space x launched a rocket. There is no avoiding it.
Autonomy is something fucking amazing. I imagine millions of articles are published per day. 99% things said before. What part should I want to read? The 1% with the most traffic?
You should get on the train to nowhere just like everyone else - they say. Stop wandering around on your own, you should get on the train just like me!
I'm not usually telling anyone not to get on the train. If people want to discuss "rss is dead" for the ten thousandth time, let them. They think they chose the topic themselves.
There is 13 billion years of history, 6000 sq km of earth, 7.9 billion people alive, 100 billion dead, 8.7 million species of plants and animals, 350 thousand chemical compounds, 130 million books since the printing press, 100 billion stars in the milky way alone. What to spend my time on? The Trump investigations? Really?
I'm sorry for not being very technical.
