I love the idea of Webmentions, yet I've not had the time to implement it on my site. At a high-level web mentions let you comment, like and reply to other content on the web and have it be visible to that content without being centralised with tools like Disqus (which I am keen to remove from my site). Web Mentions are split in to two components, the sender and the receiver.
My site is entirely static. It's built with Hugo and hosted with Zeit. I'm pretty happy with the setup, I get near instant builds and super fast CDN'd content delivery and I can do all the things that I need to because I don't have to manage any state. I've created a simple UI for this site and also my podcast creator that enables me to quickly post new content to my statically hosted site.
I recently returned from a trip to India to attend the Google4India event (report soon) and to meet with a lot of businesses and developers. One of the most interesting changes discussed was the push for more content in the language of the users in the country, and it was particularly apparent across all of Google's products which ranged from making it easier to search in the users language, to find content, and also to read it back to users in either text or voice form.
