Unlike social media microblogging, there’s not a great story for continuing the conversation of a blog post that’s part of the IndieWeb. Replying to a blog post most often takes the form of a reply...
It'd be super cool if we could connect article-hosting services with the power of activitypub or something but like one of those commenters mentioned, the issue would always be spam and security.
In my experience, the most readable response format are replys on some link aggregator (lemmy, hn, ...) and a link to that thread in the original post.
Doesn't ActivityPub kinda solve this? Now social media comments go directly to your blog's comments, it seems pretty ideal, don't even need to embed Mastodon or whatever. It's right there.
