At the State of the Word address this week, Matt Mullenweg was asked about support for the plugin, and he commented that less than 5,000 sites had installed it. So he wasn't sure how interested people are in it.
So... if you have a WP site, let's start installing that plugin and making more sites available via ActivityPub! 😀
@warrows He was talking about installations of the plugin in WordPress installs. When you install from the central plugin repository, they gather a count of how many sites have installed a plugin. And that number shows on the plugin page, and can help give people considering a plugin a sense of how actively the plugin is used.
