I couldn't get any other site to load. Not even google.com.
It made me want to create a website called "lowbandwidthsites.com" or similar that is itself minimal and just lists the sites that you can load when there is low bandwidth for news etc.
A low bandwitdth read-only repeater for sites like reddit.com would be handy. Or maybe a general purpose low bandwidth repeater that can take any site - a bit like outline.com/mysite.com but even lower fidelity - just returns the markdown!
Edit looks like it has been done: https://www.textise.net/
