I'm yet to update my Blog's content to AMP as mst of the articles appear to be full of jargons which just bounces over my head.

However with WP plugin, I'll give it a shot and see if there's a real value out of it for the blog.

Also, will there be a built-in preview for AMP pages, or we have to do validation, like this article talks about: http://www.simplilearn.com/how-to-validate-accelerated-mobile-pages-quickly-via-google-article ?
