If you need even more control, you can request the conversation as JSON from apps or scripts by adding
format=jsonfeed to the URL. Or you can add
format=jf2 to produce output that matches Webmention.io, so it’s easier to repurpose tools that already work with Webmention.io.
Speaking of Webmention, this is not just about taking Micro.blog-only replies and putting them on your blog. Because all Micro.blog-hosted blogs support Webmention, and Micro.blog can accept mentions even from blogs that have not yet registered on Micro.blog, with Conversation.js it now becomes much more useful for other blogs to send you replies. Those replies can appear on your blog, with Micro.blog mostly acting as glue so that both blogs can talk to each other.
I’ve been wanting to do something like this for a while. It didn’t take long at IndieWebCamp Austin when I finally sat down to code it, but I think it opens up a lot of options for Micro.blog in the future, including acting as an IndieWeb-friendly replacement for Disqus and other commenting systems.
