This article has some interesting websites to tie travel planning with social networking. Crowd-Sourcing for Travel Advice - NYTimes.com It’s no surprise that travelers tend to trust the advice of people they know.

Take Gogobot.com and Afar.com, which both made their debuts last year. Each allows users to post specific questions about pcoming vacations to both Facebook friends and users of the sites: Where are the best family-friendly restaurants in Paris? Should we hire a personal driver to get around El Salvador? “It’s not who you know, it’s who you need to know,” said Derek Butcher, chief technology officer of Afar Media, which also publishes the two-year-old travel magazine Afar.
