We all use twitter to read daily thoughts of famous people, friends or unknown men.
But yet year ago could we think it can be as popular as example of explosive growth — Digg.
Now they have same spread level: each control 0,021% of US traffic (number of visits).

“Last week, the market share of visits to Twitter surpassed Digg for the first time since launch and was ranked #84 (one above Digg at #85) in the Computers and Internet category. A big driver of traffic to Twitter last week was around the US Airways plane crash in to the Hudson River last Thursday, driving many posts and updates about the situation. One photo of the plane taken by Janis Krums, was viewed by many people via Twitter and was subsequently used across a number of traditional media outlets.”
