Ditto. I went through the list on Mashable ( http://mashable.com/2014/04/09/heartbleed-bug-websites-affected/ ) and changed what needed changing. I've not yet checked other sites for which I have logins that were not in Mashable's list, though I could/should be doing so at either LastPass ( https://lastpass.com/heartbleed/ ) or 1Password ( https://heartbleed.agilebits.com/ ). This is mainly because I'm super lazy, but also because, like you, I've got a unique password for each site. I feel less urgently inclined to change those passwords on sites that are largely unimportant to me. That's possibly the equivalent of "Put my fingers in my ears and chanted La-La-La-La" and, if so, I'll just have my own laziness to blame.

Btw, if anyone's got a good list of sites whose passwords need changing, a la Mashable's but more complete/updated, I'd be much obliged if you posted the link.
