Facebook Selfdestruction

I witnessed a major case of selfdestruction via Facebook these days: a former colleague posted a few messages abou how curious he was on friday. He was waiting if Friday would be his day of success. If things were really that simple that you just have to tell people that you are the best. That he hoped that finally he would achieve something.
He works in the lower management of a worldwide software company. Some frieds were curious and asked, but he did not tell any details. Until friday: that’s when his tone switched to disappointment. And after having been asked a few times, he - as an actively employed manager at his company, who even publishes his employer in his facebook-profile - confessed that he had applied for a new job and did not get it.
That’s not only stupid, that’s really disloyal and reputation damaging towards his employer. Such a behaviour is a real personal career booster…
