Indeed, nothing bad about having marketing skill or excelling at it. Certain people can take average glass skill and, through marketing, networking` and product savvy, parlay it into greater fame and fortune than others - people who have been pounding at their craft for decades.

Building a brand is a skill many artists don't excel at. It requires similar people skills to being a salesman. Often they have to rely on dealers, gallery owners and store owners who have the people skills to do retail and wholesale more successfully. The situation is somewhat mirrored in tech with the schism between programmers and CEO/investor/founder type personalities.

In the niche I work in, some people got lucky and became 'famous' in a kind of underground video way on Instagram and Snapchat. These days it's starting to resemble a more traditional art market.
