Although Flip.com, CondeNet's answer to MySpace, doesn't officially debut until February 6, that hasn't stopped approximately 10,000 teenage girls from already pre-registering.

The site, which features a combination networking/artsy-fartsy scrapbook vibe looks to have a strong following among preliminary users, and CondeNet editors are already pleased—and surprised—by their early success:

Since beta began on Dec. 27, about 1,500 "flip books" have been created, with about half of them labeled as private and half set to public viewing. But unlike MySpace, the personalized flip books are more than just photo albums of the prom or last night's bender. The artistic handiwork of the users — who were invited into the site during its beta stage from Teen Vogue's It Girls network and via e-mail lists from YM.com and Style.com, among others — easily could be used in portfolios to enter design schools or even as commercials themselves. "We're surprised by the level of ambition," said Pallot.

All of which, of course, is bad news for the 'Toos and Elizabeth Spiers, who are both looking to corner the tween girl (a.k.a. "underage hotties") market with their respective web ventures.

Meanwhile, MySpace execs have announced they are currently less concerned with attracting beautiful, impressionable girls to their site, and more focused on devising means by which to block those nubile young teens from the much larger proliferation of really creepy old guys.
