Hitwise: Visits to Gmail Surpass YouTube

Finally, Hitwise reported on the top three sources of traffic to Gmail year-over-year, and the majority of referrals, as could be guessed, is Google itself with 48.83%, up 10% since last year. The runners up are Facebook with 4.37% and Yahoo! Mail with 4.29%. Yahoo! Mail referrals dropped 18% from last year. To us this appears that while adoption of Gmail is growing, it may be as a result of people choosing one web mail provider over another.
