Well, I think I've cracked it - after a few weeks of on-and-off work on making my webmention sending not spam everyone (see https://www.jvt.me/posts/2019/10/30/reader-mail-webmention-spam/ ) - it's now not re-sending them if they're successful. This is a good first step, but I'll be improving it to re-send if the post's data has changed since last time it tried (in the future). Note that this isn't quite done yet, expect it to be live tomorrow perhaps.
Testing out Malcolm Blaney's relatively new Unicyclic feed reader. Very clean and simple! I love that it handles Twitter feeds in a much more natural way than any of the big corporate feed readers out there. Of course the fact that it supports micropub is also a major bonus! IndieWeb tools FTW!
