A simply awesome article, that I would refer to back and again, can someone please refine this with his comments as well. I mean it would be really helpful to point out any mistakes Pinterest did, at any point, what I want to know is, what could they have done better. Also, business is a dynamic environment, so somethings might have changed, so can someone please also point out, if something was right when pinterest did it, but now there are better alternatives. Thanks a lot in advance. I would be really reading many of the comments properly. ~Rika
