Romain Dillet, writing for TechCrunch:

The WordPress team has followed the project and worked on its own implementation of AMP. Starting today, any website on WordPress.com now automatically supports AMP. There’s nothing to do. Self-hosted WordPress websites can also enable AMP by installing a plugin.

I’m still skeptical about this whole AMP thing. But if I can add support to my site, with little effort, and improve the experience for my readers, I don’t see why I wouldn’t.
