Maybe someone was like me and they didn't think to not search for their password which ended up on their browser history. The title had password leaks in it and that's the first thing I thought of when I got there: "Hey my MtGox password got leaked lets google it."
For that matter, I have a unique password (with the necessary special characters) for each account that associates with my identity (Not naming any examples here), but only several unique passwords for websites I don't intend to use much e.g. to read newspapers, and apparently, MtGox.
(Yes, I was searching for my MtGox. password because it was the same password I used for random throwaway sites. No I never used it, I don't even remember having confirmed my account there. My asset in bitcoins amount to < $2 USD.)
I still don't understand why all the downvotes. It would've helped me if someone reminded me not to actually google my password with my browser watching. Apparently not anyone else.
And for that matter, why do you have so few that you can easily google for them instead of generating random ones per site?
(Fun fact, googling for your e-mail address reveals a hash of your password on MtGox.)
