Everyone knows not to read the comments on the internet, but far too often you reach the end of an article and the comments are just there, and you get stupider as a result of reading them.
This app works as an extension for Safari, to block comments across the web, and help you keep your sanity.
The First Rule of the internet is "Do not read the comments" and it is a lot easier to follow that rule if you never even see the comments.
For the odd site where you do want to enable comments, there is an option in the app to turn off the blocking for any particular website.
