Regarding the Facebook login being a part of Qihoo, I wouldn't expect any changes. Remember that Qihoo is a publicly traded corporation (New York Stock Exchange) with about 40% Institutional ownership. The guys on Wall Street just DROOL over any social media presence (like Facebook) for the stocks that they own. So basically it's like this- Qihoo's market cap is about 11 billion USD. People who have invested about 5 Billion like the Facebook icon. Geeks like us hate it. Any guesses on who will win?
