My slides from the seminar I held in Huntingdon on October 1, 2009, titled Everything You Ever Wanted to Know About Social Media but were afraid to ask.
White papers and additional resources available at http://fasterfuture.blogspot.com. Quality cartoons included by Hugh McLeod (GapingVoid.com). You'll find many more in hi book Ignore Everybody. Bad graphics authors own :-)
Clipping is a handy way to collect important slides you want to go back to later.
