I don't 'social network'.
However, since this seems to be a thing of the moment, I find it to be the perfect Darwinian selection tool, sometimes.
Some people's desire to advertise every aspect of their lives seems to override their ability to realize that it may, at some stage, conflict with the interests of other individuals or entities.
Especially when said 'entity' is the one who employs you under the terms that will keep cognisant of their rules and publications, which happen to mention that no photography shall be made aboard the flight deck without proper authorization...
Don't get me wrong, I feel bad for the guy. But then why, aside from vanity, would one expose himself in such a sensitive way?
Besides, chicks don't like pilots anymore. We don't make any money...
