Looks neat.
If it’s going to be like HN, then it needs the front page to have posts voted beyond a threshold. Right now it shows the latest, which is like going to the “new” section on HN and seeing all the submissions pouring in and waiting to appear on the front page. Maybe the front page showing top posts with recency could help. Health is another area where there’s a lot of clickbait articles and spam. So controlling the quality of posts on the front page is very important.
