Is There a Real Estate "Bubble?"?

My question to the public in general is, " Do you feel as an informed consumer that there is a Real Estate "bubble" ready to burst?" And if you care, as I do as a Realtor, from where did this "bubble"talk originate? Just answer with comments to either A) Economic statistics as they relate to jobless rate/ interest rates/ current affairs or ; B) the media and its hype? Please post your ideas, opinions and answers as I will post my feedback soon. Thanks, Jay.
