John Carter spoke on Social Networking to a combined group of PMUG and the local PC Club yesterday. He’s posted the pdf under Benefits < Tips and Tricks. Go here to the PMUG website. You’ll find an extensive report that would take 133 pages to print out! (John didn’t just do this off the top of his head!)
His report identifies the top social networking sites and discusses Protocol, Problems, Password, Privacy, Photos, and Possibilities.
