In a world of unwritten rules, one would never attempt to eat sushi with a fork or show up to a job interview wearing a costume unless you happen to be applying for a position as a clown (or wanting to be clowned).

One particular travel site, however, is taking a different approach than the rest of the players in an elite group of meta search engines in the online travel space. Mobissimo has embraced social networking and personalization tools to a degree that far exceeds its competitors (Kayak, Sidestep and Farecast).

Powered by Plum, this area of the site allows visitors to create a space to share all their travel-related urls, images, videos, notes or documents. It’s like a scrapbook of travel ideas. With MobiShare you can create shared folders where friends can contribute and anyone on the site can comment on the content or discover new places to visit.  MobiShare adds to Mobissimo’s MobiFriends travel community where you can meet travelers from around the world and share the fares you find on Mobissimo.

Other than including a “Deals” section on their sites, true meta search engines have been known to keep a minimalist’s approach in design so that the main focus is on their bread and butter – search. However, with travelers taking fewer trips this year, consumers want to make sure they’re getting the most out of every trip so Mobissimo’s strategy to differentiate by adding a fully integrated social networking component may well pay off.

Historically, Kayak/Sidestep and Farecast (with much greater funding) have had stronger overall U.S. traffic growth than Mobissimo, whereas Mobissimo has had stronger international brand awareness. As a result, Mobissimo’s social networking initiative to grow organically within its own ecosystem may also prove to be a good sticking point for its worldwide user base, keeping visitors engaged longer and driving incremental customer acquisition.
