Loading of 3rd party commenting scripts, and other integrations
The comment sections on this website require a button press to load. This page explains why.
When a website loads a Disqus script, your browser has to send a request to Disqus servers to get the content. This allows them to know what page you are on, and they use this information to build up profiles on people to later serve them advertising.
This website does not load comment plug-ins until explicitly requested by the user, by clicking the Load button. This prevents the comment provider from knowing you are on the page unless you actually interact with their widget. You can see how it works in the comments section of this page. It also has the benefit of making pages load faster!
