I'm not not interested in this idea.
I think the hard part would be coming up with ideas and writing copy for the calendar. Illustrations are time consuming but straightforward (and fun), and there are probably plug-and-play services for manufacture and distribution.
One project I'm working on is compressing EA-related material into tweet form (eg), and a curated selection of these could form the backbone of the copy.
I've made a note in my calendar on September 1 next year to revisit this idea and see if I've got enough raw material for put something together for 2024.
If someone else wants to participate (writing, ideas, illustrations, or even accountability check-ins), DM me or leave a comment and this'll be much more likely to happen.
I think GiveDirectly gets special privilege because "just give the money to the poorest people" is such a safe bet for how to spend money altruistically.
Like if a billionaire wanted to spend a million dollars making your life better, they could either:
You'd want them to set a pretty high bar of "I have high confidence that the thing I chose to spend the money on will be much better than whatever you would spend the money on yourself."
