They are definitely out there. Micro.blog is an entire community of diverse people with this practice (admittedly with some technophiles scattered about). You can easily set up an account and pipe a feed of your content into that network and participate from your own site (for free). If you’re into education and related topics, you’ll find people like Maha Bali who are part of the Domain of One’s Own space which is similar to #IndieWeb. Perhaps I’ll list some more for #FeedReaderFriday?
