The United States Army just released the second edition of their Social Media Handbook. Its 48-pages of detailed information include everything from instructions on how to start a blog to what not to tweet. The tips in the handbook essentially fall into one of two categories. The first category is made up of pretty useful social media tips that apply to everyone; the second comprises of quasi-cryptic instructions on how not to embarrass the Army or get someone killed because of a tweet. Since the Army's first handbook came out in January, the world has shown us how powerful social media can be, both for its potential and its dangers. The Army has taken note and passed them along to our nation's soldiers most directly with a list of DOs and DON'Ts for Facebook and Twitter. We've quoted some of the more interesting ones below.
