I have now set up Micro.blog to pull in posts from my main (external) blog via its RSS feed, and auto-cross post stuff from here to Mastodon.
Webmention machinery is set up using Webmention.io, so should replies to my imported main blog posts here get sent as webmentions automatically? And assuming that the imported main blog post also gets cross posted to Mastodon automatically, should replies on Mastodonn end up as Webmentions too, or do I need to hook up brid.gy for that?
I am getting there slowly, but there is a lot to get to grips with!
