I keep wondering if lemmy itself could do a decent job of this, and that being native to a communities style platform is a good thing for a blogging platform on the fediverse.
I'm a big fan of tools made for purpose. Lemmy has some fantastic features and continues to improve, but it was never designed as a blogging platform. Even when I duplicate self text posts, it doesn't merge. In the timeline. I like Lemmy and want to see it succeed. Though that's not easy with the ML administration team going rogue or the overt centralization fostered on world, but neither of those are software issues.
