Deletion of Groundswell (book)

Comment: the book is used by at George Washington University as an assigned textbook- http://www.gwu.edu/~gspm/academics/syllabi/pspr/fa08/201spellman.pdf, it's been used in academic reports http://www.cunacouncils.org/download/white_papers/wp_social_networking_marketing_tool.pdf, and it's been mentioned in two books http://scholar.google.com/scholar?q=%22groundswell%20harvard%22&hl=en&ned=us&tab=ns.  That's |barely enough for me
Stance: keep
