Donations as an alternative commerce

HI,

Im intrested in your viewpoint on private donations.

For me its another way of financing ideas, like if you would buy something (Se-Pay-Use), with the difference that you pay after you are satisfied with it after have been using it (Se-Use-pay?).

Its like giving something with a good thougth behind, not like when you have to pay your taxes or buy a product you wonder if it will be good fo you.

I also wonder how the Blender Foundation is mainly financed. By EU and International funds, or private donations?
