I know what you did last summer: What can we learn from photolog?

I know what you did last summer is not just the title of a movie trilogy of a serial killer but increasingly the feeling experienced by many on the net. In this paper we explain this interesting phenomenon that has emerged through photologs, public image sharing applications that are widespread in the Web and still growing. Since 2004, people around the globe have been talking about this application that allows for mass-photo sharing. A photolog or photoblog is a specific type of weblog that allows one to order digital photos systematically, often in chronological order [1]. For many, the photolog is seen as an alternative to the online photo album, which was introduced earlier and is familiar to most online users. The photolog is a form of social software application that allows people to collaborate and connect, that uniting many users through photographs; Flickr 1 , Fotopages 2 and Fotolog 3 are well known examples.
