I like to think that the word "oracle" is based on the Oracle at Delphi (I don't know this for sure, but it's plausible). And like the Oracle at Delphi, how we interpret an oracle can be at least as important as what the oracle actually says.
Emperor Nero - the guy who fiddled while Rome burned, killed his mother, and generally wasn't the most civil rights oriented of emperors - went to the Oracle at Delphi. He was told:
Your presence here outrages the god you seek. Go back, matricide! The number 73 marks the hour of your downfall!
Nero seems to have thought this was great. He was 30 at the time, so he figured he'd have 43 more years ruling Rome and then die at the ripe old age of 73. Not too shabby!
Nero was killed just a few years later in a revolt led by a 73 year old man. The oracle was right. The interpretation was completely wrong.
Now, the Oracle at Delphi was notorious for this kind of behavior: they'd say something, someone would think, "oh no problem" and then get his comeuppance through an interpretation he hadn't thought of. See Shakespeare's Macbeth and the witches for another example.
We need to be careful about our modern oracles for the same reason. There's what the oracle says, and there's how we interpret it, and those may not be the same thing. Please, use oracles. Just be careful to check your interpretation occasionally.
