In plain words
Jamn.io is a social media platform launched in March 2022 that organizes content as a weighted directed graph rather than traditional feeds. The platform structures connections between users and content with numerical weights that influence how information flows through the network. It is designed for users seeking an alternative to conventional social media architectures, offering a more mathematically explicit model of relationships and information distribution.

Hi HN! I made many small web games in the past with Unity or Phaser. But this time I wanted to make something completely on my own. So I coded a basic game framework in plain JavaScript, and used it to make Almost Pong. This was a really fun project that taught me a lot about JavaScript, and I plan to make more minimalist games with this framework. Interesting fact: Almost Pong doesn't load any assets, all sprites and sounds are generated with code. Happy to answer questions, and please let me know if you have any feedback on the game. Thanks!
