Show HN: Kardius – find people like you, near you – made with Rust and Rocket
Congratulations on launching and on the architecture choice and dev insights!<p>With regards to the product, there are several consequences you are about to see and need prepare to mitigate. I worked on something similar and need to rewrite it, thus the learnings.<p>1. The site looks like a dream come true for political recruiters&#x2F;promoters. You have a place full of users self-identifying with political labels in great detail and you can reach out to anyone. You will see a ton of spam from companies, parties, surveyors, you name it. You may want to throttle it by limiting number of new people that can be reached by a user in 24 hrs.<p>2. Scammers or predators could bait people into in-person meetings or worse. All they have to do is mimic the typical profile of their targets. There is no verification of truth in others, but there is a lot of personal exposure of yourself.<p>3. It was strange to see people’s likes and dislikes as a profile. It gives you a lot to potentially dislike in a person, but nothing really to draw you to them as a person. In a community, the more preferences one lists, the more odds they have of alienating their neighbors, instead of bringing them together. Labels and stereotypes have one thing in common - they pidgeonhole people instead of giving them personality.<p>You have shown you can execute. The above is just feedback on the inherent intended or unintended consequences behind this new funnel for mixing people. Social products can be quite dangerous but also fun. It’s critical to reduce downside risk.
