Is It FREE ??

I'm puzzled.....what is the VALUE of FREE ?
No I'm not a deep person, just curios what you might think. Here's where I'm coming from. I manage a RE/MAX office in Ann Arbor, and the last office meeting we had in November, I encouraged all the agents to sign up for a Point2Agent web site for FREE. I have been using it as one of my 5 sites for about 2 years. Last year I upgraded to the professional because I wanted to be able to add all my listings to it, not just the 7-8 or allowed on the FREE one.
I am working with a client moving back from California in January from seeing a listing on my http://MissyCaulkTEAM.com Point2Agent site. It will be well worth the small amount I pay for more listing exposure.
Still no one in my office has signed up. Why ??? IT'S FREE !!
I have invited 26 people to join the Active Rain community, only 4 have accepted. Why not ? It's great fun, a new skill, meet lots of people, learning community and is it because it is FREE ?
My assistant for 9 years and I were going to do a training class at the office on Microsoft Outlook as we have been using if for years. How many signed up ? ONE
Now Zillow is going to let us put our listings on Zillow for FREE. hummmmm I wonder how many agents will sign up for that ?
In a slower market, I believe we do anything and everything to get our houses sold, to improve our skills.
Does anyone else have this problem ? Is the value diminished because it is FREE ?
