I was surprised to receive $5k in donations this year, while working towards our premium featureset. It has created high hopes for some real recurring revenue in the next 1-2 months when those premium features are released. But yes, the donate button along with a simple paypal payment setup was very easy and the amount of donors continues to surprise me. Then again, if you count up the hours spent with no revenue, the $$$ per hour is very small. We were recently surprised to be approached randomly by a second company (first company approached out of the blue as well) asking if we would license our stuff. I guess this is a decent example of an unexpected revenue stream, requiring a slight pivot in revenue model.
