Would you date your friend's ex?

Hello all,

I was reading last week's issue of "Jet". The relationship topic was "Is it okay to date your friend's ex-boyfriend/girlfriend?"
Jet usually has four or five experts in the field and they usually have a variety of opinions. This time they seemed to agree that is not a good idea, no matter how bad or peaceful the break-up was.
I agree with this. I think, scratch that, I know that it causes major problems. I'm sure most people will agree, but there are those who differ. Has anyone ever experienced this? If not, what is your opinion? What would you do in a situation like this?
