All of the links are from my Fresh RSS. Works great. Ive curated my rss feeds for more than a decade at this point. Theres also services that can create rss feeds for you if you google.

Also Tumbler works with rss as well as royal road (for books).

royal road: https://www.royalroad.com/fiction/21220/mother-of-learning/ is https://www.royalroad.com/syndication/21220 FreshRss will generally find the rss feeds pretty well if you put the full url in there.

Hope that helps!
