This comes from a reader: Yesterday Yahoo announced it would begin offering 100 megabytes of storage to its non-paying e-mail subscribers in a direct attack on Google’s fledgeling Gmail service which promises 1 gigabyte. Currently Yahoo e-mail only stores 4 megabytes for non-paying customers. This could make Yahoo e-mail (questionably?) more attractive than Gmail, as Yahoo e-mail will have comparable storage without the privacy (non) issues associated with Gmail. Currently Yahoo charges $49.99 a year for 100 megabytes of storage, which begs the question, how will they make up that lost revenue?
