Ask HN: Long-form blogging syndication technologies for 2018

I'm returning to long-form personal and professional blogging after a many years off/away. I intend, initially, to follow the Just Write And Hit Publish approach, and (re)learn as I go. However. One question in the back of my mind relates to syndication. I am under no illusion that my writing will be any better or worse than any others, but I am keen to make sure those who read blogs regularly (or, perhaps more accurately, in preference to social media feeds) have the mechanisms to plug my stuff into their stuff, should my words be of interest to them, with the least resistance. There's RSS. There's Atom. Those are well-known to me, having been around for a while, and they work. There's Open Graph and schema.org for metadata that provides a platform to share. There are all sorts of other things out there…and I'm not sure what to offer technology-wise. What sharing/syndication technologies are worth looking into for a 2018 blogger, please? I'm especially curious what reading tool(s) you use if you're a long-form reader. Thank you for your time.
