personalized start page category
“A lot of the growth in the personalized start page category has historically been kickstarted and is still derived from internal and external distribution deals, not organic or viral growth. The original My Yahoo of ten years ago received an incredible amount of traffic from the main Yahoo.com portal (and it still does), and the same went for iGoogle when it launched in 2005 – that little “iGoogle” link in the upper right hand corner of the standard Google.com page was the engine that drove (and continues to drive) traffic to the site.”
