@Cambridgeport90 I don't worry about them stepping on each other, I simply make sure they're cross-linked so that if I go looking for something, I'll be able to find it. Webmention definitely helps in this respect.

As an example you'll notice that my earlier response (http://stream.boffosocko.com/2021/roberthaisfield-i-agree-wholeheartedly-and-have-written-a-bit-about) links to part of the related commentary on my main site, so there will be a webmention in the comments there that ties it all together.
