I had a lot of fun doing this exercise and found some beautiful photos from places I'd been to when I visited Europe in 2006. I had never used Flickr before but think it is way cool! There seem to be a number of ways of exploring the site (I used the map of the world where you could search by location or tags). What a great idea for people to be able to share their photos with others. I can also see that I could waste hours playing on sites like this!
