Keeping records

I was thinking that few of us actually keep records of our written conversations. But then I remembered Stephen Wolfram’s “The Personal Analytics of My Life”:

I actually assumed lots of other people were [collecting personal data] too, but apparently they were not. And so now I have what is probably one of the world’s largest collections of personal data.

I have a complete archive of all my email going back to 1989.

Check out the figures.
