It’s not so much that blogging died but that commenting on them directly did, and with it blog culture. Commenting now takes place in other venues, not visible to the blog’s reader unless that venue is where they came from. HN is part of that of course.
I wrote my own blog engine in Python (https://github.com/betodealmeida/nefelibata). It generates static pages, but publishes a snippet to Twitter/Mastodon/etc., linking back to the blog post.
People can only comment on the social media sites, and periodically the comments get scraped and appended to the blog post. Here's an example: https://blog.taoetc.org/mastodon_integration/index.html
This way, people can comment in the other venues where they're used to, and comments get persisted past the lifetime of these venues.
