Static sites are becoming more and more popular -- you can host them on CDNs across the globe, they can be cached client-side, pre-loaded, work offline....

Especially important thinking about the billions of people in developing countries accessing the Internet over 2G connections.

If the trend towards static sites continues, Netlify could be the next Heroku.

Personally, I use Netlify to host my Gatsby blog; all I need to do is `git push` and they handle the rest.
