Real estate agents have disproportionate commissions largely based on where they operate. A real estate agent in San Bernardino, CA may make $1K for selling a home, while an agent in Palo Alto makes $10K+, because, well, the house costs 10x as much. Disclaimer: My father is a broker in San Bernardino. He's mentioned to me a number of times how incredible it is that agents get to take a percentage of the selling cost rather than a fixed fee. "Doctors get rich by going into real estate," a famous quote of his.
Certainly there is more competition for agents in Palo Alto, but the actual amount of work done by a real estate agent in PA is damn near equivalent to the work done by one in SB. There are standard California forms, inspections, financing etc. The only "added perks" provided by luxury firms in the Bay Area are aesthetic improvements designed to attract wealthy buyers.
For those who are interested, innovation in the real estate market has been difficult due to the monopoly on housing listings. The "Multiple Listing Service" (http://www.mls.com/) is the only master directory of housing lists and is only made available to "Realtors". In case you didn't know, Realtors are not exceptional agents, they simply pay to be members and gain access to the MLS. My dad was a member for the longest time just to have access to the MLS. After all, when a customer asks you to help buy a home, where are you going to get your list of available properties from?
In order for Open Listings to succeed they're going to have to upset the MLS. This means building their own listings. Here's my (crazy) suggestion: Hire 20+ people to drive around the Bay Area looking for "for sale" signs in order to populate their database. It's what my dad and I used to do before he paid to be a Realtor. Once we had a list of available properties we could show them to clients.
