Admiral James G. Stavridis is the commander of US Navy European Command and is also Supreme Allied Commander, Europe.  He recently spoke to students at the National Defense University, encouraging them to “read, think, write” —  even blog:

Share your ideas in print — a scholarly journal, a military magazine, a literary journal, or even a blog post…Is there “career risk” in publishing? I suppose. It hasn’t hurt me too badly over the years. What matters more is testing your ideas on the field of intellectual battle, so to speak.

Despite the fact, as noted, military regulations largely haven’t caught up to the social media age, the Admiral became only the latest senior military leader to encourage members of the military to write publicly, and even blog.
