There's a big rumor going around that Facebook had to sell 10% of its shares in order to pay for enough hardware to handle the rapid increase of users in the last year.
It looks like the article first appeared on the Times Online UK edition, and has since been removed. There are a few snapshots of the article floating around on the Internet from readers that caught the Times post before it had been taken down, indicating that the company had an urgent call for cash last year with its rise in users.
The story seems a bit over the top, and is most likely untrue. It doesn't make much sense, given the revenue and amount of funding Facebook has received. Zuckerburg has set up Facebook with the intent of maintaining control over the site for a very long time, and seemingly continues to do so, even in the face of a possible acquisition. So we'll sit back and wait for an official word from Facebook.
