Yes, LinkedIn is in the news but not quite for the purposes originally intended…the Chinese espionage community recognized LinkedIn as a great tool for looking up German bureaucrats and enlisting them to spy, and where did they start?
By offering to connect to them, I suppose.
Morale of the story: don’t connect to random people you don’t know or cannot meet or get to know.
Keep your LinkedIn profile clean and be associated with people in whose company you want to be seen. Period.
