Wordpress is a very nice publishing platform that is very easy to install and use. Unfortunately with its plugin system it can become very bloated and slow.
This site uses ghost. It uses node.js. It is much faster than wordpress, but your typical shared web hosting doesn’t support it. This site runs on a small Google cloud compute engine instance.
If you can’t/don’t want to use Google cloud and can’t find a hosting provider that will support node.js you can also try hugo. Hugo generates a static site that you can upload to almost any type of server.
Edit: this site is now generated by hugo and runs on standard hosting on a small VPS server at Vultr (Affiliate link). All of the above is still valid.
