Tripartisan is a news aggregator (similar to HN, reddit, or voat) focused on politics. The key difference between Tripartisan and other aggregators is that it asks users to identify their political stance on signup. Users choose between three broad categories: left-leaning, right-leaning, and neither. This makes possible a number of features which don't exist on other aggregation sites. For example:
1) You can see not just the number of votes a post or comment has received, but what the partisan distribution of those votes is.
2) You can sort posts by partisan affiliation, or use the "best" sort, which prioritizes posts that received votes from across the political spectrum.
3) When viewing a user's profile, you can see both the partisan distribution of the people who upvoted that user, as well as the partisan distribution of the posts/comments that user upvoted.
I'm hoping that this explicit partitioning of users could help prevent the echo chamber/hivemind problems suffered by other political news aggregators like r/politics or voat. At the moment Tripartisan just a prototype, but I'd be interested to hear peoples' thoughts on it (both the concept and the implementation).
