This is so cool! WordPress is absolutely crushing it!
"The WordPress ActivityPub plugin has been updated to version 2.0. The major feature of the release is better comment federation... “When you respond to comments from the fediverse on your blog, they will now be federated. This allows you to finally engage in (threaded) communication back and forth directly from the comment section of your blog!”
