David Hobby, over at strobist.com, gives a great example of how to put together a nice little no cost property site using the free blogs anyone can get at blogger.com. You can get similar blogs at wordpress.com for free. Wow, I hope David's listing agent appreciates what a fantastic client she has. I've never seen a listing client do this much work to market their home, or one that shoots this kind of photos!
Free blogs are a wonderful resource. You can have as many of these blogs as you want. I always have ten or more of them at a time. I use them for things like family reunion photos and videos or other events. The biggest use I make of them is I create a blog for each listing my wife has and use it to give showing feedback (I ask every agent that shows the listing to give me feedback about what their client thought of the home) to the homeowner. Homeowners love the detailed feedback... unless it's bad and then they hate it! But the detailed feedback makes it hard to hide from the truth.
