Today Jordan Chark published a list with 75+ US travel sites at Mashable. He recently wrote a similar post called Travel Hacking: Essential Sites for Summer Travelers. I link to these instead of updating and enriching my own List of Travel 2.0 and Social Travel Site.

Note: Thanks to Jordan’ s diligence and his post SHOPPING SPREE: 18 Sites for Social Shopping & Deals the same cost-efficient updating mechanism could be applied to my List of Shopping 2.0 and Social Shopping Sites, but that would be too much of resting on laurels of others.
