Colin McKay, a Canadian Government communicator and blogger and social media pioneer extraordinaire, has written The Secret Underground Guide to Social Media for Organisations. It is not a technical guide. More a cultural, managerial guide to avoid the roadblocks set by IT and legal departments. Colin has blogged about it himself.
At 23 pages it is a quick and enjoyable read.
