Interesting startup started by 15 years old girl and a 16 year old boy. And guess what they have garner US$17m in funding.

We started myYearbook in 1 high school with just our friends. Now we have 5+ million members and billions of page views per month because all our features come straight from members.

Pretty amazing results. The market in US is just so vastly different.. Things get viral and spread fast. However I really wonder how they sustained with facebook wildly popular. And they have tapped into facebook with many widgets!
