NEW YORK (TheStreet) -- Yahoo (YHOO) has become less of an Internet company and more like a soap opera. Third Point's Dan Loeb added more drama, again calling for CEO Scott Thompson's head as the proxy battle between Yahoo and hedge fund firm Third Point, its largest shareholder, goes on.Loeb released another letter today, asking that Thompson be fired following the disclosure that his education background was not what it seemed. "It appears very clear to us -- and to many corporate governance experts, Yahoo employees, and fellow Yahoo shareholders -- that Mr. Thompson's fantasy degree was in no way an 'inadvertent error.' The evidence shows he had been using false credentials for years. Mr. Thompson's 'apology' was clearly insufficient and it seems that the only thing he actually regrets is that he has been caught in a lie and publicly exposed," Loeb wrote in the letter.
