At 5, the clock radio at the hotel started playing Steely Dan. I knew it in less than a second. Two notes.
Same thing happens when I see just the edge of the New Yorker sitting in the pile of mail or the formatting of an email from a friend. I could probably tell a Starbucks just from the sound and the smell of the store. They all have brand DNA.
Do you? Does your blog? Your company? I don't think it happens by accident.
