I think Gary Vaynerchuk is great. I love his store—Wine Library—and I admire his energy. His book Crush It sounds truly inspiring. But I don't think his can-doism is the key to success in all areas. And he comes off sounding glib and a bit naive when he shows GalleyCat how to apply his methods to succeeding as a short story writer.
It takes more than time, energy, and social networking to succeed as a short story writer. Vaynerchuk throws out the phrase "creating great content" as if it's purely a matter of will. But talent is something you can't will into existence. And developing talent takes time, patience, a capacity to improve, a certain kind of stubbornness, and a particular sensibility that isn't necessarily compatible with haunting chat rooms and leaving comments on blogs. Would Gary V. say that someone could succeed as a football player by blogging and twittering? I don't think so. You might find a game to get into, but that doesn't make you a pro.
