rss-bridge has done wonders for my ability to keep up with a lot of different blogs, youtube channels, etc.

I have considered writing bots that can bring content from outside the fediverse into it (say, by autoposting links to videos from an youtube channel), but really rss-bridge and feed readers are so much better. They are also private in the sense that I don't have to broadcast to the world who I am following.
