As a creative, when is the last time someone asked for your resume? You probably haven’t been asked for a resume in a very long time, and that’s because your potential employer has figured out other ways to check you out and see if they relate to you and what you do.
What people actually do these days is Google you and assess your talents based on your website, portfolio, and social media profiles. Since people are now hiring based off how they can relate to and identify with you, the bio is your best bet to convey that. Trust comes from personal disclosure. And that kind of sharing is hard to convey in a resume.
