For whatever it's worth, HPMOR introduced me to Effective Altruism and lesswrong, etc.

Though I found it online and not from the $30K distributed, I have since as a result of being introduced to Effective Altruism there donated much more than $30K to highly effective charities and caused hundreds of other people to get into donating to highly effective charities too. I also started a company inspired by the EA concepts of working on "neglected problems" - https://80000hours.org/articles/problem-framework/#definitio...

I might be wrong, but I suspect there's a decent chance there was at least 1 person like me of the people in that $30k distribution.
