Starting next week, the Internet is going to look very different -- and ICANN Chief Executive Fadi Chehade is the one who'll get both the credit and the blame.

But starting Feb. 4, the first of hundreds of new GTLDs will begin arriving -- .ninja, .farm, .shoes, .photography, .bike, .pink, and even .wtf.
