Description
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)

Could you build this?
Yes Scraping Lobste.rs public user pages and rendering the hierarchical network graph using off-the-shelf JavaScript graph libraries (like Sigma.js or D3.js) is easily accomplished with vibe coding.

Same idea, different domain
Nobody's really built a analytics & bi tool for Legal yet.
