I've written a 4-part series about the aptitudes, abilities, and skills for content strategists, along with some of the things to look for when hiring a CS and a reading list for those wanting to expand their skill sets. The first of the series can be found here: http://intentionaldesign.ca/2010/06/09/world-of-content-strategists/ . As always, feedback, comments, and supplemental information is appreciated.
