In the online field, more than in any other I know, personal branding is compulsory. And by that I mean absolutely unavoidable. Your online presence will work while youre asleep, while youre on holiday, while youre working hard on a new secret feature. Maintaining a solid, persistent online presence is the key ingredient to a successful personal branding. Dont assume people knows everything about you, constantly reinforce what YOU want them to know about you.
