It seems everybody’s throwing money at Facebook nowadays.

In October they got a USD240 million investment from Microsoft, which resulted in a USD15 billion valuation.

Not bad for a 3-year old company founded and headed by a 23-year old, another Harvard dropout who has been dubbed “the new Bill Gates.”

They are now perhaps the world’s social networking site with the highest valuation.

Now even 79-year old Li Ka-shing, the richest man in Asia and the 9th richest in the world, has thrown his support. He invested USD60 million recently, and has the right to invest another UDS60 million if he wants to.

Li was introduced to Facebook by an existing investor who contacted Solina Chau, director of the Li Ka-shing Foundation.

Facebook is now apparently the world’s 2nd most popular social networking site, with more than 73 million members. MySpace is still the runaway leader with 289 million members. In contrast, Friendster, arguably the most popular site among Malaysians, is at 13th place with 26 million.
