Yesterday, I decided to reorganize my 'Archive' folder of my private mailbox.
My policy is, don't remove e-mail except if it's spam
And I noticed some 'growing' of the number of e-mails per year in the archive:
 Year | Number of mails | ||
2003 | 133 | ||
2004 | 530 | ||
2005 | 706 | ||
2006 | 865 | ||
2007 | 1869 | ||
2008 | 2335 | ||
2009 | 2832 |
So some nice graph of it will be:
