More on LinkedIn Profiles

When someone views your LinkedIn profile, the first thing they notice is your profile picture - and within as little as 80ms, an impression is formed. The rest of your profile either supports that initial impression or is in conflict with it - the latter not being the ideal scenario.
When you see Griffen's new headshot (great job Griffin!) for his profile, that initial impression is one of confidence, approachability, competence. And the rest of his profile supports that.
Your LinkedIn profile is your resume, or thinking of yourself/your career as a business, it's your storefront, your website, your brand. You want all the elements of your profile to work together to present the best of you.
