If your password is any of the above, you should definitely change it. Some hackers blast through a list of email addresses or usernames, testing them against the most common passwords.
My advice is to change all of your passwords to secure ones, and make sure they are different for each site.
Ideally, you should use a long password (16 characters or more) with combinations of uppercase, lowercase, numbers and special characters. Short and simple passwords are very easy to hack.
Choosing a new password can be tedious and tricky when trying to come up with a password which passes the different rules that different sites use, so I created a free tool which lets you choose which types of characters you need to include in your new password and then it generates one for you.

To manage all of these passwords, you can use a service like LastPass which stores all of your passwords in a secure vault and it uses a high level of encryption. There are even some password manager services that change your password for you periodically with these other sites, so you don't even know what your password is.
I've started to just use the forgotten password functionality on most sites these days, so I can set a new password, use it at the time, forget about it and when I need to login again another day, just use the forgotten password process again.
Look after your friends and family's security online, make sure they are aware of this and get them to secure their accounts.
