'Which social networks do you use the most to boost your career—and why?'
LinkedIn is good for keeping tabs on old friends and, um, enemies. It's also great to get all Chuck Woolery and make new "Ad Connections," by passing notes like, "I think your ad is neat. Do you think my ads are neat? Maybe we can get together over some ice cream and comps. Please check yes or no." —Joey Crawford, senior copywriter, ML Rogers, New York
The more I get into online networking [LinkedIn, Hyves (biggest network in the Netherlands), Facebook], the more I also start to appreciate the "old skool" personal networking by meeting people in bars, seminars, airports, supermarkets. 'Cause let's be honest, an actual relationship only starts with a handshake. —Mark van Egmond, managing director, BSUR Agency, Amsterdam, the Netherlands
I'm on Facebook, LinkedIn and Twitter. LinkedIn is useful as a business contact repository, but Facebook is a lot more fun. . . . It gives a different sense of connection that LinkedIn doesn't. —Mark Kingdon, CEO, Organic, New York
Most useful is my own makeshift social network that consists of the marketing-related blogs I read regularly on my RSS reader and the people behind them. —Ilya Vedrashko, emerging media strategist, Hill, Holliday, Connors, Cosmopulos, Boston
Newcreatives.com. It's a great database of young creative talent. That's more or less it. —Tom van Daele, cd, Duval Guillaume, New York
iRovr [is] a network designed exclusively for the iPhone, and I find it to be a great source of inspiration for what's really happening in the trenches when it comes to "cool." —Spike Stevens, director, interactive strategy and creative, Thomas Taber & Drazen, Denver
Here are the numbers for my personal LinkedIn account: 180 people are in my network. The people they know and the people those people know are 2 million-plus worldwide. . . . My last job and a six-figure contract were both a result of utilizing that network. —Craig Stevens, director, business development, VGS Creative, Westport, Conn.
Facebook and LinkedIn. On Facebook, it's exciting to get new updates on your friends' activities. And from a business standpoint, it allows me to stay in touch with old colleagues and maybe, more importantly, meet new ones. I also love the Spartan look of Facebook and that is 100 percent geared to the user experience. I find LinkedIn a little prosaic and devoid of personality. —John Moore, svp, director of ideas and innovation, Mullen, Wenham, Mass.
