The rumor about Microsoft’s interest in taking over Facebook was partially true, according to one of the Wall Street Journal’s sources.

Microsoft approached Facebook with proposals to invest in the startup that could value the fast-growing site at $10 billion or higher, said people familiar with the matter.
If those talks bear fruit, Microsoft could purchase a stake of up to 5% in the closely held startup, at a cost in the range of $300 million to $500 million, the people said. Microsoft already has an agreement with Facebook for advertising and considering the fact that Microsoft doesn’t even have its own social network, this move could be reasonable: apparently Google too is interested in a similar investment.
