I think we’ve covered this before BUT this is a slightly different approach to the idea.
Derrick Waddell has created a Facebook template for historical figures. This template, available through the Google Docs public template gallery, asks students to complete a Facebook profile for famous people throughout history. The template has a place for pictures, an "about me" section, a friends column, and a map to plot the travels of historical figures.
This almost works for me but the ‘real’ audience is still lacking – I wonder if the school could host these pages on their websites? – and allow comments?
