Are those real celebrities asking those questions?!
Question:
Are those real celebrities asking those questions?
Because I don't know.
Answers:
Either Yahoo! Answers suggests the question for them, and they approve (not them, the people who work for them).
Or Yahoo! Answers invites them to be a part of this community, and people who work for them take care of everything, from asking and all.
That is what I think :)
