PC World’s Eric Geier went and found out. Turns out, an eavesdropper can get usernames, passwords, and the contents of your messages. And hijacking your accounts is a cakewalk.

It’s easy to avoid this. Just look for https in your browser’s address bar whenever you are browsing from a coffee shop, and make sure it stays there.
