A new travel social network is getting ready to launch.  TripWolf.com.  From their site:

-Our new facebook integration allows you to log in and import your profile and social
graph (eliminating social profile fatigue)
-Our content partner who provides professional content
-Professional and user-generated content
-Portable data – downloadable PDF content
-wiki-approach – users can add/update information
-‘trip gurus’ offering knowledgeable local advice
-Site is available English and German language
-Personalized recommendations among users
-Covers the whole world with over 200,000 points of interest

I’m looking forward to seeing how it turns out.  I think the ‘portable data’ in PDF form is a great marketing phrase, and seeing original content is always a plus.  I’ll keep you updated on this project as they are still in beta.  You can visit their blog and stay up to date as well.
