I wrote about my 2023 donations at length here.
TL;DR:
90% to the Against Malaria Foundation (only GiveWell-recommended charity with a Canadian entity)
5% to a local harm reduction charity (local charity that probably saves the most lives per dollar donated)
5% to a local financial aid clinic (expected ROI of something like 20-30x cash)
I really like your lamp post analogy! The world is big and the more EAs practice looking under their own lamp posts and writing up what they find the better the community will be for it.
