Ugh! Just having the thought of having to teach Object-Oriented Databases gives me headaches---I haven't dealt with Databases for quite some time and seeing yet another paradigm would just be insane.
It makes a real mess on your account. So, I would advise you o create a dummy account if you intend to use it "seriously" (and don't forget to encrypt what you think is sensitive information). But it is a damn nice hack.
