Wow, great move by Automattic.

Open sourcing front-end that among other things connects to WP REST API? Brilliant!

And the Mac app? Slick. Like Slack on Mac.

I reckon that in the future Jetpack connection for self-hosted sites will be made entirely obsolete and that Calypso will fully communicate through REST API endpoints. And Calypso forks that will communicate to endpoints published by plugins and themes? Heck, perhaps ManageWP is getting serious competition this time :)

Only surprised by the sensationalist reports that WordPress is "dumping PHP for Javascript" which have nothing to do with this.
