A State Department official warned students at Columbia University's School of International and Public Affairs this week that discussing WikiLeaks on Facebook or Twitter could endanger their employment prospects.
The official, a former student of the school, called the career services office of his alma mater to advise students not to post links to WikiLeaks documents, nor to make comments on social networks such as Twitter and Facebook, as "engaging in these activities would call into question [a student's] ability to deal with confidential information, which is part of most positions with the federal government," he was quoted as saying in an e-mail sent to students by the career services office on Tuesday.
The reason we are able to talk about these documents is because someone else leaked them, thus even though the government may have classified them in some way, it really doesn't matter since they are essentially public documents.
Certainly you wouldn't want to brag on Twitter or Facebook that you posted confidential information to the Internet. That would be career-limiting.
