After days of learning how to use `fedify`, I finally managed to get it to work so you can now comment from the Fediverse! Search nw@blog.northwestw.in on your Mastodon-like instance and follow it to get federated! As a side effect is implementing this, I had to also create a database to handle the Fediverse stuff, so this ended up taking forever to integrate. (Now if only the comment loading script actually works...)
Blog posts are sent to the Fediverse as `Article`, which unfortunately means you won't see the full post but only the summary. I could send the posts as `Note`, but that seems like abusing the system. So for now, you'll still have to read the full post on this site.
