The latest e-business report from ACSI, The American Customer Satisfaction Index, has some bad news for Facebook -- and by extension, yet more good news for Google. The survey, produced in partnership with customer experience analytics firm ForeSee Results, found that despite a small 3 percent jump in its score, Facebook ranks as the lowest-scoring site of all companies measured, not just in the social media category. There are likely many reasons for the low score of 66, said Larry Freed, president and CEO of ForeSee.
