I agree. Wordpress powers something like 40% of all websites. 40% of the web having a low friction way of publishing to the fediverse is a big deal. Sure, this doesn't mean that almost half the web is suddenly "on the fediverse"; the more ad-dependent a site is, the less likely it seems that they'll enable this unless they can do so in a way that brings users to them.

I want to be able to have a fediverse feed that's as much RSS feed as news feed, but that's my preference. I'm really glad WP is making it easy for folks to use ActivityPub.
