I'm sorry, but whenever someone says google this or google that I have to speak up. Google is overhyped and overrated. They weren't around 5 years ago and they may not be around 5 years from now.
Real estate is a UNIQUE industry and yes they may capture some marketing dollars but there is ALOT more to it then that... which is what most of the non-agents on this board don't understand. It's different from one town to the next and what works one place doesn't in another... plus google is making enemies left and right (and so is hv... in a BIG way) so.... I say someone will come along with something better sooner or later ..... they always do.
