A Harvard Law School student has filed a class action lawsuit  against Google on behalf of Gmail users.

According to the Crimson, Eva Hibnick claims that Buzz discloses personal information without consent and constitutes a breach of privacy. What has got her miffed is that Buzz allows users to “follow,” or track updates posted by, their e-mail contacts. She said it was social notworking gone too far.

Google has since changed to the program , but continues to be an “opt-out” program, meaning that Gmail’s 31.2 million users are automatically signed up until they choose to deactivate Buzz.

The lawsuit appears to be a bit of a homework project and is backed by to Law School professor William B. Rubenstein, who specialises in class actions.
