If you are looking for new things to see while visiting a holiday destination, this site might be of interest. http://www.sightsmap.com/
It shows a heatmap of where people have taken photos (hurrah for EXIF & GPS data). Mike and I were looking at it last night to see where else we might want to visit in Japan. It seems a good way of finding places that guides may not have suggested but are worth a visit for the view. Zooming in gives you the individual photos and markers for the sites in question.
Thought I would share
