Rob Fisman reports on The Huffington Post:
Talking about WikiLeaks on Facebook or Twitter could endanger your job  prospects, a State Department official warned students at Columbia  University's School of International and Public Affairs this week.
An email from SIPA's Office of Career Services went out Tuesday  afternoon with a caution from the official, an alumnus of the school.  Students who will be applying for jobs in the federal government could  jeopardize their prospects by posting links to WikiLeaks online, or even  by discussing the leaked documents on social networking sites, the  official was quoted as saying.
"[The alumnus] recommends that you DO NOT post links to these documents  nor make comments on social media sites such as Facebook or through  Twitter," the Office of Career Services advised students. "Engaging in  these activities would call into question your ability to deal with  confidential information, which is part of most positions with the  federal government."
While the massive disclosure of once-classified documents detailing some  of the nation's most tightly-guarded secrets has inflamed allies and  enemies alike, the move by the State Department represents a new front  in the administration's campaign against unauthorized leaks.
Philip J. Crowley, spokesman for the State Department, denied in an email message any federal involvement:
This is not true. We have instructed State Department employees not to  access the WikiLeaks site and download posted documents using an  unclassified network since these documents are still classified. We  condemn what Mr. Assange is doing, but have given no advice to anyone  beyond the State Department to my knowledge.
When asked why Columbia — which confirmed to the New York Times earlier  today that an email had been sent from its offices — would have sent the  message, Crowley said, "If an employee of the State Department sent  such an email, it does not represent a formal policy position."
Earlier this week, companies like Amazon and PayPal shut off the  services they provided to WikiLeaks, threatening the site's survival and  impeding further dissemination of its treasure trove of classified  documents.
Now, however, it appears the federal government has moved beyond  staunching the flow of leaked information, to suppressing even the very  mention of WikiLeaks online by prospective employees.
