I look back when we first started real estate back in 1998 and have deduced that Technology and the internet will be two things that will catch on. (wink wink).
When we first broke ground in Real Estate it was easy to see how the "real estate agents", at the time, were able to keep their industry such a secret. With very few books having been written about real estate, investing, or where there was no "on line" source one could scour to do research - they were like the Great and Powerful OZ!
Today, things are a lot different. You can type questions into Google. You can ask for opinions from Google, Bing and Yahoo with Qualifying factors, such as Top, Best and Most.
You can also put in qualifiers for Worst, Bad, criminal and others that are "negative" in nature.
