Stockfighter: Patrick McKenzie (patio11 on HN), Thomas Ptacek (tptacek on HN), and Erin Ptacek.
ESR's homepage: Eric Raymond.
I can see why someone might find something from Yarvin or Raymond less cool after looking (even a little) at Yarvin and Raymond because they have some controversial opinions outside of tech, but I've never heard any such things about the Stockfighter people. In fact, two of the Stockfighter people have the two highest karma accounts on HN, indicating that generally their opinions line up pretty will with the majority of HN. What did you find uncool about them?
Things that seemed cool until I looked (even a little) closer at the people behind them: urbit, stockfighter, and ESR's homepage.
