Perhaps the Kinja developers should take a look into this note by not-coppervines:

This is completely off topic, but I don't see anyone talking about it much, and nu-Kinja bugs like this should be known.

I am not coppervines. By now, I have been automatically logged in to no less than three different user accounts when accessing a Gawker Media site. As soon as I log out and log back in to my actual account, navigating to another page will either log me out, or log me in to yet another user's account.

So, just a heads up, everyone. Other people potentially have access to your accounts, and password security has nothing to do with it.
