All of us at WhatTheyThink use LinkedIn and I know a number of our members are on the professional social networking website. Yesterday LinkedIn confirmed that a hacker had gained access to its user database. The hacker has already posted a dump of over 6 million hashed passwords as proof.

We strongly recommend that you follow LinkedIn's recommendations and immediately change your LinkedIn password. If you have used your LinkedIn password on any other websites change those passwords too.

If you need to change your WhatTheyThink password you can do that in the Member Center.
