Too lazy, apart from my bank password and programs/websites that use my credit card I won't be changing shit. I couldn't care less if my Fakku password was stolen.
Sorry to be a bother, but I hope you'd also change your e-mail passwords (to avoid the possibility of someone using access to your e-mail to reset the passwords of those important accounts you mentioned). If you have all your important accounts linked to a single e-mail, it shouldn't be too much trouble.
If you've already had, awesome. I just thought I'd say it as a reminder for you or anyone else reading this who want to just change the important stuff (I feel that since it doesn't directly use credit cards numbers for anything it's importance might be overlooked if you think only about sites that use them).
