I had the extreme pleasure of sitting down with Peter Clayton of Total Picture Radio last week while at the Kennedy Information recruiting conference in Las Vegas. Peter and I discussed a wide variety of recruiting-related social networking topics including MySpace (4,300% traffic increase in two years, most visited networking site with an 80% share, third most visited U.S. Internet site, over 31.5 billion page views per month, and an average user age of 35). We also talked about topics such as LinkedIn, Facebook, and Second Life.
