The issue name “micropub for bridgy publish” sounded a lot like what I was looking for in https://chat.indieweb.org/dev/2018-02-26/1519669277072200 but this issue is clearly about adding Micropub support as another API to Bridgy Publish, rather than adding another Bridgy Publish target to Micropub servers (for which I’ll file a separate issue).
Perhaps consider renaming this issue to something like:
Micropub API to Bridgy Publish
and I can file an issue for: Bridgy Publish to Micropub servers
Thanks!
