Bullshit Matt.
The internet has just added another dimension to the marketing of real estate, but it has proved quite innefective as a selling tool. Everyone thought that the internet would take take the agent out of the equation but it hasn't done shit.
I have worked on both sides......in commercial agency and now in development. Of all the marketing tools at our disposal, the internet has proven to be the most worthless.
You say the most successful agents have connections.......that's the whole point.......you need to get out there and knock on doors, ring people, network etc. to be a good agent.......listings won't just magically walk through the door.
Cold calling is all part of the job...........it's the good communicators and those not afraid to wear a bit of shoe leather out who will succeed.
