I presentation I gave on June 10th 2009 at Trentino Sviluppo, local agency in charge of developing local businesses. It is about the how and why (and why not) of using social networking systems such as Facebook or Twitter for small businesses. The slides are released under Creative Commons By-Attribution so share them, play with them, tear them apart! The only exception are the two photos below for which I don’t know who the copyright holder is. If you know please get in contact with me. Thanks!
