Here are a few links I like to send out when it comes to questions on how to use new/social media. There are many more resources out there, including some nice short videos on twitter and social networking. In fact, just thinking about it now, it would be nice to have a page of links that allows votes and comments for each resource, as well as anyone could add additional ones. While I'm not feeling that ambitious at the moment to go out and create such a page (perhaps one exists already) I have a few links from the DoD, Air Force, and UK Government Civil Servants that I find useful.
Here are a few links that I like on social media usage and recommend:
-- Web 2.0 policy development on Intelink
-- Also, the Web 2.0 guidance forum with many insightful commentaries
-- Good commentary on OPSEC and a little bit more on good social media common sense
-- AETC plans on using social media, comments add perspective
-- UK government guidance for civil servants: a well thought out, yet simple way to communicate the culture of new media and best practices for responsible use
-- This is a simple pamphlet style guide. Highly recommended reading!
