Web monitoring site Pingdom is reporting that in 2010 alone, there were 107 trillion (that's 107, 000, 000, 000, 000) emails sent worldwide. Out of the 107 trillion, 10.9 percent of it were actual emails, the rest? Spam.
Supposedly there are 1.88 billion email users worldwide, 255 million websites (21.4 million are said to have opened in 2010). Twitter is a defining force on the web with 25 billion tweets last year and 100 million users added in 2010. Facebook of course takes the cake with 30 billion pieces of content (links, pics, videos, etc) each and every month!
Facebook also added 250 million users in 2010. Insane.
