How about we store them in some KeePass database [http://keepass.info/] and still upload it to, e.g. Google Docs, but lock it with a master password? That way we only have to remember one (like @krzys_h wanted), to open the file and the rest can be as complicated and secure as we want them to be.
Edit: I've missed @Simbax's post up there, sorry. :/ It doesn't invalidate my point though, I still consider one master password to be quite reasonable. Definitely better than having different password for everything, like we do right now and in case someone actually forgets then, well, I guess that person would just do what everybody's been doing already and ask one of the admins for it.
And let's not forget the social engineering skills of desperate people.
