Moving on from Feedly and rebooting my RSS feed list

I'm fond of quoting Clay Shirky's from an interview he gave over a decade ago:
I know people who get everything in their work environment just so, but current optimization is long-term anachronism. I'm in the business of weak signal detection, so at the end of every year, I junk a lot of perfectly good habits in favor of awkward new ones.
He specifically talked about switching RSS feed readers, which I'm also intending to do at the end of this year. I've been using Feedly for some time now, and was a premium customer for a while. But I think I'm ready for a change.
I'll probably install something like FreshRSS, Miniflux, or Tiny Tiny RSS on the Njalla VPS that's serving this site. And I'm thinking of starting from scratch, in which case I want to have a backup of my list of feeds. This is known as an OPML file, and you can find mine below.
I'll no doubt document my setup once it's all up and running. There are some people's work that I definitely don't want to miss, so I'll be adding those straight in.
But I want to avoid the anachronism that Shirky talks about, hence mixing things up at the end of this year and the start of next.
