Flickr... better way to share photos

Wow... what an amazing technique to use and to be able to geotag photos, videos and audio files. What a great way for educators to take students on virtual 'field trips' around the world. Students can use flickr to upload their own photos and compare and contrast their way of life/culture with others from all over the world. Pretty cool... here's my flickr account (very simple and small so far) to check out: http://www.flickr.com/photos/martyk555/
