The Defense Department, which had seen some services ban the use of social networking sites, will allow troops and their families to use the popular online communication tools such as Facebook and Twitter on its unclassified networks, according to a draft memo obtained by Nextgov.
The memo, written by Deputy Defense Secretary William Lynn III and due out in days, solidly backs the use of social network sites, which Lynn calls "Internet capabilities," for both official and unofficial purposes and envisions these tools as providing an information advantage for Defense.

The directive defines Internet capabilities as "the full range of publicly accessible information services resident on the Internet [and] external to the DoD, [for example] outside of the .mil domains, including Web 2.0 tools such as social networking services, social media, user-generated content sites, social software, as well as e-mail, instant messaging and discussion forums."
