Show HN: Kardius – find people like you, near you – made with Rust and Rocket
The website is nice and easy to use and the concept is fun. I love hierarchical clustering so the technology also appeals to me. But I was very disappointed by the nature of the cards, I expected hobbies or personality based card whereas almost all those I got were about political issues. Who chooses their friends based on their opinion of Brexit? That seems very unhealthy. Maybe I was unlucky.<p>Another thing is that even for non-political topics. The clusters that are drawn end up being political. You like anime? -&gt; Libertaniarism cluster. You like research? -&gt; Free speech cluster. If you dislike Libertaniarism suddenly you no longer match up with people who like Anime. That&#x27;s the danger of unsupervised learning, it might be interesting to impose some constraints on it so that you can control which topics get compared together.
