Facebook is going great guns and it has grown really big. According to the recent S-1 filing submitted to the Security and Exchange Commission (SEC), the social networking site presently caters to 901 million active users monthly. Facebook user base rose by 33% in the last one year.

Facebook is visited by about 526 million users every day that comes down to 58.3% of the total active users. In addition, around 488 million users used the Facebook mobile apps in March 2012. This is certainly a great achievement.

But, the financial front is a little shaky for the social networking giant. The profits of the company dipped to US $137 million in the first quarter of 2012, a straight fall of 10.7% for the same period of the previous year.

All-in-all, Facebook is in a good position to go public in May 2012. So, do you still have second thoughts on why you should be on Facebook?
