Germany
Did i mention that in the last 4 years i spent ~2920 hours in this website and earned ~3000 Eur in 4 years? Thats ~1.03 Eur per hour of work :D
If I had invested the same time in a part-time job at McDonalds, I would have earned about 41,580 Eur.
I think this answers the question why I do it: Just because and because it's fun.
