Pandora sued for frictionless sharing

You know how, if you use Facebook and Spotify and aren't too careful, how all of a sudden everything you listen to gets pumped out to the wider world? Pandora introduced a similar feature a few months back.

There's now a class action lawsuit being gathered in Michigan, which claims the sudden wittering out of 'now playing' information to the usually-more-public-than-you're-expecting Facebook is a breach of a promise the service made to keep everyone's tastes private. If successful, it could cost Pandora $5,000 a user.

Not quite frictionless, then.
