Thanks. I find it funny that some people who consider themselves rational and open minded are very easily discarding methods like this as superstition without hearing out what you actually have to say.
I believe Tarot cards are a somewhat similar way of gaining understanding of your own preferences.
In my opinion yes, any kind of oracle that gives you ambiguous answers is more or less equivalent: I Ching for me is convenient because it gives a relatively compact result (while doing tarot reading requires you to pore over a dozen or so cards and all their relationships, which to me risks to muddle things up).
