Tired of searching for references always in the same way? This weekend a friend introduced me to tag Galaxy. This is a site with a very different navigation. It is done in Flash and is searching for tags in the directory of Flickr. The site is extremely well done and I would even say that is quite fast. You select a TAG, the site displays a planet with this Tags and some minor planets with sub categories. When you are in the category of your choice, you click the planet and it opens to a 3D photo collection related to the category sought. I found a fun way to search and referrals.
