Let go of information... holding onto it can destroy the new home sales process. 
In the best selling book "Idea Virus," Seth Godin likens the spread of information online, to the particles of an infectious virus.
Note this is not just theory, but an observation of how effective messages move through the lines of digital communication.
Information technology has broaden the width and depth of our world online, and offline as well. By shortening long distances, new online social tools and web apps have exponentialy increased the number of messages to us all... (think Twitter.)
This constant influx of information often overloads one's ability to effectively interpret and properly categorize a majority of these incoming messages; thereby creating a need for information aggregators.
Here's the "opportunity" for the new home sales pro:
The fracturing of traditional offline information into mobile bite-sized info bits is creating a seemingly endless supply of emerging micro-real-estate-markets.
Why not be the local information aggregator for your new home community?
Online home buyers prefer their home search information to be well filtered, and thoroughly refined... why not research and aggregate all of the home buying related information for your area.
Then use your new home sales blog to filter your competitors' real estate marketing and sales messages to the bottom of the search engine pile, and present yourself as the local micro-real-estate-market expert.
That is good information. Sounds like you are on to something here.
