Hacker News is a link aggregator and message board that I check on a daily basis to read about the latest news in computer science and entrepreneurship topics.
I created a user style for Stylish / Userstyles.org that you can install to your preferred browser to override the default Hacker News styles.
To install this website theme you will need to install Stylish. Stylish is available for Firefox (and other Mozilla programs) and Chrome as an add-on or extension.
The user style is open source and you can fork or contribute to it on Github
