Every media company should be afraid of Flipboard. The Palo Alto startup epitomizes the best and the worst of the internet. The best is for the user. The worst is for the content providers that feed its stunning expansion without getting a dime in return. According to Kara Swisher ‘s AllThingsD, nine months after launching its first version, Flipboard’s new $50m financing round gives the company a €200m valuation.

Many newspapers or magazines carrying hundreds of journalists can’t get a €200m valuation today. Last year, for the Groupe Le Monde, an investment bank memo set a valuation of approximately $100m (net of its $86m debt at the time, to be precise). That was for a 644 journalists multimedia company – OK, one that had been badly managed for years. Still, Flipboard is a 32-people startup with a single product and no revenue yet.

So, what’s the fuss about?

The answer is a simple one: Flipboard is THE product any big media company or, better, any group of media companies should have invented. It’s an iPad application (soon to be supplemented by an iPhone version), it allows readers to aggregate any sources they want: social medias such as Twitter, Facebook, Flickr or any combination of RSS feeds. No need to remember the feed’s often-complicated URL, Flipboard searches it for you and puts the result in a neat eBook-like layout. A striking example: the Google Reader it connects you to suddenly morphs from its Icelandic look into a cozy and elegant set of pages that you actually flip. Flipboard most visible feature is an interface that transform this:

All implemented with near perfection. No flickering, no hiccups when a page resizes or layouts adjust. More
