Remember that your email is part of your password. When sites are compromised your email is never encrypted and when you use the same email across every site a hacker now has part one of your login. For those unlucky to use the same password across many sites, once the password is obtained it can now be used at other sites. If you have a unique email (login) to every site then using the same password becomes less of an issue as the hacker now only knows 1 part of the authentication values. Still best to use different passwords though.
