HBGary's employees, particularly CEO Aaron Burr, were obsessed with the use and abuse of social networks (here's the HBGary Email Viewer: Portal and search engine). Others might also find this an interesting area for political research. From "US Gov. Software Creates 'Fake People' on Social Networks to Promote Propaganda":
"One employee wrote, 'and now social networks are closing the gap between attacker and victim, to the point I just found (via linked-in) 112 females, wives of service men, all stationed at Hurlbert Field FL - in case you don't know this is where the CIA flies all their "private" airlines out of. What a damn joke - the U.S. is no longer the super power in cyber, and probably won't be in other areas soon.'"So now anybody can identify the pilots (it appears that LinkedIn is particularly useful in this kind of research, but opportunities exist in every social network to turn the tables on these bastards). There must be many more cases where loose social networking lips can sink ships.
