This is one of my first side projects, and I created it because I’ve always been interested in opinion-based questions on HN (i.e. Ask HN: What is your favorite internet rabbit hole?). I know there are already several sites where you can ask opinionated questions (quota, slant, hn), but I was looking for something that’s uncluttered and straightforward. That’s why Diffur questions are simple lists. Anyone can vote and rankings are based on vote count.

Here are some topics I’ve added:
