I am staying with Yahoo
"names, email addresses, telephone numbers, dates of birth, hashed passwords and, in some cases, encrypted or unencrypted security questions and answers, were lifted."
Hmm, my yahoo e-mail address is already in the public domain on account of me giving it to other people so that they can e-mail me. If you know my name (which is in my e-mail address), then getting my DOB isn't too difficult; but that was my bad, not Yahoo's
Are anybody's e-mail providers safe? Fact is, if you want to do anything online you need e-mail, and I think yahoo are as on the ball as anyone when it comes to security, so I'm staying with them.
