A plotted history of Facebook (so far)

This just struck me as something useful to refer back to so I'm going to post it so I can find it later. Which could prompt me off on a course about information aggregation / sharing / remembering which of the many places it might have been catalogued in depending on my mood at the time, but luckily I'm desparately trying to cull my 80+ tabs in Firefox down to something more manageable so time is short. Much to read.
