A very, very interesting news about the internet came up to me today while I was checking out Google Reader. It is from The Guardian. The internet has reached the point where it is called 500 bn Gigabyte. If this amount of data was to be printed out, then it would reach from the Earth to Pluto 10 times. The way internet "digital tribes" are growing, they are faster than NASA's spacecrafts.
Quoted from The Guardian
About 70% of the information in the digital universe is created by individuals and includes phone calls, emails, photos, online banking transactions or postings on social networking sites, including Twitter.
