Lobste.rs makes its entire invitation tree public. I scraped it and built this interactive visualization.

Some interesting patterns:

- The top 10 inviters are responsible for ~40% of all users.

- The tree is surprisingly shallow: Most users are only 4-6 generations from the founder. Max depth is around 15.

Built with Sigma.js for WebGL rendering. Works on mobile too.

(I am seeking a lobste.rs invite if anyone's willing! – my email is in my profile)
