Onur Cobanli explains:
Design is a consultancy job; you spend years to acquire design know how and one day someone asks you a design question, do not be tempted to answer because you know the answer, remember how many years you take to know the answer and then remember my words that design consultancy in any form should be paid for, if you a professional designer never give your design ideas for free, if you are an amateur designer, never give your ideas in any case; they might as well be dangerous! Joking aside, you got my point.
