Advertisers to Facebook: Take our money, please

With a reach approaching 15 percent of the world's population, Facebook is a thriving media business. In the last quarter alone, it raked in more $1 billion in revenue, almost entirely from advertising. But to hear some people at big ad agencies talk, it could be a whole lot more. And that's the double-edged sword hanging over Facebook these days, for the company has become a victim of its own success. It's automating its process and using technology to increase efficiency. But that's not the same as dealing with a human being; big advertisers are a needy bunch who want hand-holding. However, plenty say they can't even find anyone at Facebook to take their calls -- or their money.
