Oooh very interesting indeed! Especially for raising awareness of the dangers with concepts of online privacy. If you want to make it even more random and interesting, why not have some characters of your own creation? You could make as many paper cards as you have students, and write down a couple pieces of information on each card (e.g. "32 year-old Chinese-American college graduate"; "21 year-old lesbian"; "male primary school teacher earning $xx,xxx a year"...). They draw a card at random, and have to make up whichever information isn't on the card as they sign up on FB (having to come up with realistic profiles). As a youngster (on FB), I'd be inspired by this exercise, and I know it wouldn't affect my own profile. Alternatively/additionally, some of the students could post wall items, notes, links and so on, whilst some other could stay silent. You could then compare the similar profile and see whether it's affected by the content? Do tell us how it goes! Bruno Masters student London, UK
