YouTube might have an age restriction that begins at 13, but that has not stopped tweens and kids from loving the site. Recent research says that 93% of tweens ages 8 to 11 say they use the site, and 69% say they have an account. However, only 28% of them say they share online videos. They are more likely to “clustershare,” which means sharing videos in person while spending time with family or hanging out with friends. (WSJ)
