Travelers arrive at Facebook
	Hatched in a Harvard University dorm room three years ago as a way to keep tabs on fellow students, the social networking site Facebook is becoming a go-to destination for travelers - and not just the type who frequent youth hostels or friends' couches.
Since opening its virtual doors last fall to anyone with an e-mail address, Facebook has graduated to more than 37 million users, and the 25-and-over crowd is its fastest-growing demographic. A key factor in the site's rapid ascent: development of more than 3,000 free, third-party software applications that let Facebook "friends" trade everything from travel tips, Scrabble scores and books they're reading to hedge fund advice via a fantasy stock exchange. The most popular of Facebook's 100-odd travel applications, downloaded by more than 2.6 million members since its launch by a freelance Web developer in June, is Where I've Been - a map that highlights places users have been to, lived in and hope to visit. The interactive map includes a smattering of facts for each destination. This month, rumors swirled - and were swatted down - that Expedia-owned TripAdvisor had paid $3 million for Where I've Been. The buzz surrounding the phantom sale to TripAdvisor, which offers a similar Cities I've Visited map on Facebook, shows the site "is certainly making on impact on travel," says Lorraine Sileo of PhoCusWright, a travel research firm. Another online travel company staking a Facebook claim is the search site SideStep. Among its offerings are Trips, a group travel planning service, and CouchSwap, which lets members find and rate free in-home alternatives to hotels. Both travel applications are aimed largely at Facebook's original member base: "We're not a brand that many college kids are aware of, and there's no better way to introduce ourselves to that demographic," says SideStep CEO Rob Solomon.
