Looks like target of your post is a programmer with years of experience that for some reason don't know how to earn few pennies. So i guess ... no one?
Why i have responded? Maybe to put some light on how great those tips are? Did you think that you will get "thanks for tips i need money but i didn't think about getting a job" answers?
Not sure if it's a language barrier thing, but you're really missing the point.
It's not the same though. You'd be surprised how many people think that the only way to acquire bitcoin is by buying it with fiat. They need to be reminded that they can also get paid in bitcoin, whether their full salary for a new job they get hired for or for their old job and part of their salary in bitcoin.
Those who are self-employed could also add the option to receive the payment in bitcoin (like a merchant selling goods for bitcoin to whoever that asked for it).
Fortunately someone gets it.
