Give me a gift
If you want to send me a strong credible signal that you like what I am doing and thing I should be doing more of it, one way to do that is to send me money. I am not promising anything in return, unless we have separately agreed to that.

If you want to hire me to do something, my current rate is a quarter-ounce of gold (~$350) per hour or one ounce (~$1,300) per full workday, currency negotiable. This is based on the replacement cost of my time, so rates are negotiable if it's work I think ought to get done anyway; mostly I end up working for free, for glory, or for an informal equity stake.
Working on a sabbath or other previously reserved day is extra, more like a pound of gold (~$20,000).
