Tigermail, the University’s Google e-mail service started this semester, does not have all the characteristics and qualities of the standard Gmail account, though experts say some missing characteristics are beneficial. One characteristic missing from Tigermail is the use of Gmail’s controversial sidebar advertisements.According to Google’s Web site, Gmail uses an automated scanning system to find key words, prompting advertisements specifically targeting the user. The ads are displayed on the right-hand sidebar, and contain Web sites relevant to information in the e-mail. There is potential in data mining, such as scanning information and punishing unconventional viewpoints or disqualifying people for health insurance based on health issues, said Nelson Richard, mass communications professor. ”Data mining is not totally benign,” he said. “There is a potential for harm…As of now, this is legal.” Other missing applications are Gmail Lab features, which include features such as tasks and quick links, and personalized Gmail themes. —-Contact Steven Powell at [email protected]
