No clear travel 2.0 winner?

The Web 2.0 Awards by SEOmoz, an Internet marketing and search engine optimization consulting company based in Seattle, felt there was no clear leader to award winners in the travel category. I agree, somewhat, and think there is lots of opportunity for emerging travel companies out there to stake their claim. Let's check out the Travel category Honorable Mentions:

Jumpclaimer
This website enables a traveller to digital pins on a world map. Friends and family can then follow the progress. (They) do this by accepting a simple SMS containing the nearest town to you. (They) do some analysis to find the latitude/longitude coordinate of the nearest town with that name using your previous location. This is then plotted on a Google map.

Kayak
Check out previous post on Kayak.

Travbuddy
This website makes it possible to share travel experiences, travel reviews, and travel photos.

TripMojo
The company provides search results for hostels and hotels. Ability to tab between list and (another mash-up) map view. You can also check hotel details and book from a formlet that takes you to Orbitz.

Wayfaring
Web-based tool to create, use, or share information about their travels and the places in their lives

Pretty clear to me Kayak is the winner out of this bunch. All, including Kayak, are utilizing geography-based mash-ups, number six from the travel tech trends post. Some more elegantly than others.
