Facebook isn’t just a place to reunite with old friends and write cute little comments on your friends’ uploaded photos. There’s an application for everything, and the traveling applications are something that I’ve been checking out lately. Here are some facebook applications of interest.

Hostelbook.com application: this application helps you find the best hostel at the best rate wherever you may be traveling whether it’s in the United States or abroad. I backpacked around Europe four years ago, and we saved a ton of money staying at hostels. However, we didn’t have facebook to get quality reviews of which hostels to frequent and which ones to stay away from. There were hostel review sites out there, but facebook’s social network blows any of those sites away. Check this one out.

Where I’ve Been: Basically, you can brag about where you’ve been, but the cool thing is that you can check all of your friend’s “where I’ve been” places, and there may be someone who’s been where you’re going. There’s nothing better than a personal referral for cheap places to eat and stay.

Been There, Done That App: This one is similar to the one above, but it will also list things you’ve done in a particular city or country. I always have a hard time finding cool, cheap stuff to do when I visit a new place, and your network can help you with this if they’ve got the “Been There, Done That” application.

Trips by SideStep.com: This application helps you organize a trip with friends or family. Even though I’m not the most organized person in the world, I recognize that being organized saves you money. When you have a plan, you’ll save money, because you’ve already done the research. Being spontaneous is fun, and it has its place in your trip, but if your whole trip is done “on the fly” you’ll fall into a lot of tourist traps.

Have you ever used facebook for your travels? Do you like seeing where your friends or family have traveled? What other applications do you recommend?
