Spam

I participate in a number of technology forums. One of the forums sent me a report on July 29th which included the following claim:

… email is still king and 75% of the world’s digital knowledge is stored in email.

On a possibly related note, McAfee released a report the same day that announced that spam was at an all-time high:

McAfee announced today that the volume of spam emails has increased 141 percent since March to more than 117 billion emails a day. That means 92 percent of the email we get, assuming it all goes unfiltered, is spam.

So 75% of the world’s digital knowledge is stored in email and 92 percent of email is spam. I now need to refine my understanding of the phrase “digital knowledge”.
