Who is an interesting person?

I know this can be relative. But I would like to hear from you people. If you didn't understand the question, then let me rephrase for you.

What, in your opinion, makes a person interesting? (Or)
What kind of person would you call interesting?

From what I have seen around, this "interestingness" (I own the copyright to this word) is somewhat associated to a person's idiosyncrasies. Or should I say those who choose to be different often are labeled as idiosyncratic.

Alright, alright! Having subdued my top part of the brain, here is what I come up with. Something that might make sense to you.

I would say a person is interesting when he or she has a wider range of interests that overlaps with you and pursues them.

Your thoughts please.
