We have Facebook status updates, Twitter and now Plott is a new site promises to let you share every moment of your life as you live it. Little information is released about it at the moment but as far as I understand, you will be able to plot all of your moments on a timeline.
If this is the case, it may be a great tool for students to record their progress and experiences over the course of a year or longer. It is hard to tell at the moment but it looks like an exciting new site to watch. You leave your email to request an invite.
