Travel and photography are naturally the best companion. I love both, just like many of you. AppScout has an article featuring the globally oriented, multilingual capable photography site TrekEarth. TrekEarth allows users to display and discuss photos by regions of the Globe. The site appears to have all the necessary features of the social networking Web2.0 sites. The interface is clean and simple, unlike the mess at MySpace. Read the site feature lists here and the FAQ here.
