Designer / illustrator here. The "brand" thing is so pervasive now that I have to deal with people like the pest control guy telling me about their "brand" for their new workout clothing line. I blame the wildly successful Salt Life for this.
But nowadays, yes, everyone is a market-speak corporate person. Friends ask me about "promoting my personal brand" (or, what they used to call "showing your artwork") and use phrases like "SEO" and "market reach" in everyday conversation. Sort of putting the cart before the horse I think.
But - I wish Tempest the best!
