Pretty much only news.ycombinator.com. I haven't found much other interesting tech news sites and I don't think that my Reddit Homefeed will starting next month.
I group a bunch of RSS feeds into one megafeed. They are similar in a way and there is overlap. I might find one article that I understand or care to read a day, but they keep me up to date in a way.
I use an rss reader to follow like 50 websites. The main news sites are arstechnica, the verge, IGN, Polygon and many snaller websites that post less than once a week
Is there an open source RSS reader that syncs between your android and windows/web? Like if I read an article, I want it to be 'read' on all devices. Also preferably a solution without self hosting since I can't really do that.
I personally self host tt-rss on my freedombox. I use the web and android client. If you don't want to self host, maybe you can use Feedly. I am not sure how privacy friendly that is if that is also a requirement.
News Minimalist is one I recently added (via RSS). It use this machine learning to rate all news from 1 to 10 and then shares the top stories of the day based on your threshold
