So what's the deal with senior officers and LinkedIn accounts these days (note - this is not intended to be a criticism of the particular individual in this case).
In my day personal security was a big issue, we were told the Russians built up individual profiles on us based on sources such as the Air Force List, RAF News, local newspaper clippings, etc, and we were told/encouraged to make as little information as possible available in the public domain, not be photographed wearing Squadron badges, etc.
These days it seems that most senior RAF officers (far more senior than Wg Cdr) have LinkedIn accounts with their full service history - including their 3 years at Farnborough as project manager for reverse engineering captured UFO technology!! Is security now a dirty word Blackadder?
