I asked the question below on the EL&U site:

I read it in the main page of Yahoo (Poll):

Q - Are you at all superstitious?

A - Yes, I've been spooked.

What does spooked mean in this context?

I looked for the meaning of spooked and it seems like it means something like "impressed by ghosts or magic in the past" or maybe scared of them. But I am not sure about this. Would you please explain if it has other usages which might convey a different meaning than the mentioned example?

And after it was closed, I found in the closing box the explanation below, which I found ambiguous. Is it only a kind of personal idea, or is it definitely reasonable in English to find what "useful for worldwide audiences of the internet" is or is not? As a non English-speaker I want to know whether I should avoid it.

it is only relevant to a small geographic area, a specific moment in time, or an extraordinarily narrow situation that is not generally applicable to the worldwide audience of the internet.
