You know it is Bubble 2.0 when the internet is growing faster than ever:

"The Netcraft "October 2005 Survey" found 74,409,971 sites, an increase of 2.68 million sites from its September survey. The gain makes 2005 the strongest year ever for Internet growth, with the Web adding 17.5 million sites, easily surpassing the previous annual mark of 16 million during the height of the dot-com boom in 2000."
