LinkedIn security breach (June 7, 2012), change your password

In case you have not heard or been informed, as I was not, LinkedIn.com has had a security breach and 6.4 million member passwords were stolen. The theft was publicized on Thursday, June 7, 2012. As of June 10, 2012, all LinkedIn has done is to post a notice on its site that you should reset your password. In my case, the site remembered I was logged in from a previous visit and did not automatically log me out. I'm not sure whether that's a plus or a minus.
