@Smithums
the system powering my blog is called WithKnown (open source #indieweb ready blog engine) it comes with a bunch of plugins (twitter, mastodon etc..) you setup the blog, plugins, configure everything and that's what you see when you publish a new status post.
Sadly it does not support thread and currently you can only use the "reply" feature to twitter.
The whole concept thing is under the #indieweb protocols, motto is publish on your own blog, syndicate elsewhere :)

Indiewebify.me
Indieauth
micropub & microsub
all different components of the indieweb that you can find for different systems : wordpress, withKnown, Drupal, Jekyll, Hugo etc...
@Smithums Yes, my recipe is using Withknown as the source and crosspost to different mastodon instances, like this (does not work for replies tho)
