For every new job opportunity your blog or "personal brand" online garners you, there will be 0-? opportunities lost due to a hiring manager or recruiter being put off not even by the content of your online presence, but by the fact you have one at all. Most middle managers will not hire someone with a fledging YouTube channel or a popular blog or a weaponisable Twitter following unless the role is a public facing PR role (devrel etc). The thing is, there is no way to know about or count the lost opportunities. Grey man strategy (i.e. not early 2000s "build a personal brand" strategy) is safest for most people.
