I just launched Hackrdot, where you can read r/programming, Hacker News, and Slashdot all in one place. Once you create an account, you can bookmark posts and subscribe to the curated weekly mailing list.
I used Ruby on Rails both for the back-end and the front-end, with some basic JS.
This is the most basic version and I will work on new features such as a dark mode option.
This is my first full-scale personal web project, so I appreciate any feedback good or bad.
