There are two sides to the military's foray into the freewheeling world of the interactive Web. At the highest echelons of the Pentagon, civilian officials and four-star generals are newly hailing the power of social networking to make members of the American military more empathetic, entice recruits and shape public opinion on the war. The Web, however, is a big place. And the many thousands of troops who use blogs, Facebook, Twitter and other social media sites to communicate with the outside world are not always in tune with the Pentagon's official voice. Policing their daily flood of posts, videos and photographs is virtually impossible — but that has not stopped some in the military from trying. The Department of Defense, citing growing concerns about cybersecurity, plans to issue a new policy in the coming weeks that is widely expected to set departmentwide restrictions on access to social networking sites from military computers. People involved with the department's review say the new policy may limit access to social media sites to those who can demonstrate a clear work need, like public information officers or family counselors.
