Pinterest joins the billion-dollar network club

It's a good for pinning photos, protecting privacy and pinning your texts. I'm Bridget Carey and this is your CNET Update. It's time to welcome Pinterest to the billion dollar network club. Last month, we saw Instagram get bought up for a billion dollars by Facebook. Now, Pinterest, another social photo sharing network has been valued at $1.5 billion. Evaluation came after a Japanese e-commerce site invested $50 million dollars into Pinterest and what's so unsettling about this is that Pinterest makes no money. It holds no ads, there is no revenue whatsoever but then again, that was the same case with Instagram. You can put your money on one thing though, investors will start to integrate e-commerce tools into the site making it easy for users to buy items posted. If you haven't used Pinterest, it's a place to share interesting photos f things you discovered. It can be your own photo or bookmark something you saw online and it's presented so beautifully that you could just loose yourself on the site. Think of it as window shopping at the mall or flipping through an endless magazine of neat things. People put their signs into categories so that the more popular users are for sharing fashion, design tips or recipes but you can pin anything. Facebook co-founder Eduardo Saverin said he has to pay hundreds of millions of dollars in taxes on everything he has earned while he was a US Citizen. Saverin who has resided for the past 2 years in Singapore caused a big stir by dropping his citizenship just a few days before he would rake in billions from Facebook-going public and if you're not a US citizen, no need to pay US taxes from what you earn. It even angered some senators who proposed a law to punish Saverin and anyone who drops his citizenship to duck out of paying taxes. Saverin said he didn't drop his citizenship to avoid paying taxes and he will continue to pay any taxes he owes to the US government.
