If you want to follow a website that doesn't have an RSS feed, you can use https://feed43.com/ to generate one for a particular page when it updates. Then you can use http://bots.tinysubversions.com/ to follow that feed in mastodon et al.
Mastodon is the best way to keep up with what's happening.
Follow anyone across the fediverse and see it all in chronological order. No algorithms, ads, or clickbait in sight.
