Yes. If it's written by the author, read it. If it's written not by the author but by another author whom you would read on his own merits, probably. If it’s written by anyone else, no. (I guess technically, "Author's Preface" is a tautology, but whatever.)

I read them after finishing the book, often with a smirk of comtempt as I've developed views and ideas about the text far more interesting than the ones proposed in the preface.

I don't read prefaces, but I once watched a theatrical adaptation of Goethe's Faust that featured a beautiful Judaic twink as the demon and he was nearly nude. The girl Gretchen was played by a short, overweight German woman and I think that ruined the whole point of the play

no, only after the main text. They should really stop calling them introductions or put them on the back of the book because they either spoil the main text or talk about things you wouldn't understand without having read it first.
