Facebook has reached 350 million users in 2009 and it could reach half a billion users by July 2010.

But, as The New York Times stated last week, "the once-innovative application platform has now started to become a burden to some users."

"The company will also need to find a quick solution to the nonstop Facebook spam, which is generated because anyone can contact you and invite you to any number of events and fan pages".

Personally, its nonstop spam makes me crazy.

Once any account had been taken over by a malicious program, be ready to be spammed.

It happened last week to the FCC chairman.

It is worth to use Facebook in the corporate world?
