Lemmy has RSS feeds. Follow catalogues you like, subscribe to blogs when you like articles and the feed seems to have high signal to noise. I started with 6 feeds 2 months ago, now I subscribe to just under 90 different feeds of personal blogs, substacks, and media organizations.
Muting also works for RSS (depending on client). If a feed is generally good but posts a sponsored “deal of the day” in a way that can be filtered, you can add that to your filter.
Also, your local independent newspaper may have an RSS feed. Follow what’s going on in your neighborhood, not just online.
