Yahoo First to offer Share Option for E-mail
Yahoo announced that it is poised to roll out the first share option for e-mail users. The option would allow Yahoo e-mail users to share their e-mail with others. The company hopes to enter the social networking business model through this change in a well established application. E-mail generally is shared between one or more parties--Yahoo did not address the privacy interest of e-mail recipients of Yahoo users to opt-in to sharing e-mail content.
