Btw shadow, aside from the fact that your inability to think conceptually probably means youll never make it in the business world, your logic is flawed. You are implying if A requires B then that means B is all that is needed for A. So you are (incorrectly) extrapolating extra meaning onto what i said. Just because A requires B does not mean that is doesnt also require C, D, or E.
They are billion dollar businesses because they know how to create a good logo. Thay doesnt mean that is the only prerequisite, and given the fact that we are talking about logos anyone with half a brain would not expect me to list every other off topic attribute a successful business requires if it wants to make billions. Your brain is there for a reason please use it.
