I don't know how some people can use the same passwords for everything. I can understand 2 or 3 different ones though. If you have the same for everything, aren't you afraid you'll get hacked with your more important sites because for example... last I checked fusetalk doesn't encrypt passwords in the database... so some malicious admin can find that password and access your financial information. I keep 1 password for financial sites, 1 password for email addresses, and 1 for crap sites that I may register and view once or twice (which I also use for ATOT since I found out about that fusetalk problem).
I also have a whole bunch of them for work that obviously are not under my control so I use a program like Password Corral to keep track of them... all these programs are alike anyway.
