Google 2?

After landing $240 million in funding from Microsoft, Zuckerberg is knocking on doors of hedge funds and private equity groups in an effort to bring the investment round above $500 million.

It's a sign that Zuckerberg has ambitions of making Facebook the next Google, according to the Financial Times.

But Facebook has yet to turn a profit, one reason why it's biding its time to go public. "Forgetting" to turn a profit was a mistake many made during the dot-com bust.

Until then, Zuckerberg can only cross his fingers that his new ad model, touting improved targeting, pushes profits above the current $100-$150 million range when it launches next month.
