I like the idea of working for donations, because rather than withold value from anyone who can't afford it,
I can try to help wherever help is needed, and then those who can afford it can donate to support
my ongoing efforts.
However, I can't link to paypal without mentioning that they have historically supported the hydra of legalized corruption by cutting off support to WikiLeaks. So if anyone thinks my work is worth supporting, I prefer you just hand me some cash, or bitcoin, or have me over for dinner, or give me some coffee, or weed, or beer, or just let me use your shower...
