Flip.com:

Flip.com provides teens with an innovative way to express themselves and connect with each other online. More than just another social network, Flip offers its users powerful but easy-to-use interactive tools, inspiration from experts and editors to spark their imagination, and a stage on which to showcase their talents.

At the heart of Flip are Flipbooks — customizable, multimedia scrapbooks/zines/journals that Flip members make and share. Users can upload their own photos, songs, and videos as well as choose from a large collection of stickers, wallpaper, animations, and music. They can draw, write, add a soundtrack, rotate and size elements, add pages, and even choose page transitions; the result is a more powerful and personal way for girls to express themselves than anything else currently online.

In addition to making Flipbooks, girls can also browse and create profiles; start and join clubs; send and receive messages; share and comment on each other’s stuff; and chat on message boards.
