I’ve been thinking about a social media model where your website is your profile and where your posts live. There would be aggregator services kinda like mastodon that you submit/connect your website to and it would facilitate boosting/discovery and commenting.
Maybe it would be possible to access those comments and have them displayed on your own site too.
This is a little like hacker news I guess, except once connected each post would automatically be shared with your “home server”.
