I recently came across this site in my reading from the brilliant Richard Byrne. It is a site where students can create a facebook profile wall, including pictures and statuses to represent any number of things in lessons. I have used it to represent historical figures, getting students to write in the style of the times, and putting pictures in which represent their fashion.

The way i have used it recently is in an ICT lesson where i got students to produce a set of business document, and then as an extension got them to create a social media profile to advertise the business. Students loved this as it related to something they use every day, and interests and motivates them. See it at www.myfakewall.com
