What 20% factor can you attribute Vinomofo's success to in terms of the 80/20 rule?
I actually live by this rule as often as possible and it has served me well. As far as Vinomofo goes I would say our most valuable time has been spent on delivering the best possible product. Make it so good that your customers do the marketing for you. On the flip side if your product is shit no amount of advertising is going to save you.
