Tim Ferriss on Personal Branding
Tim Ferriss has an excellent post on personal branding. Let me add to his comments here.
1st captured your personal brand via domains, blogs, etc. (Even if you are not writing regularly to them.)
Then use this platform to promote those things you care about in your life. It could be where you work, your favorite hand cream, your kids soccer team, etc.
Talking about things you care about diversifies your online footprint and could lead to more career success. Consider how an employer is going to feel about an employee that is out there writing positive things about the company.
