Steve Groves wrote a great post today about real estate blogging and while it has a global reach, it needs local support. While I know what Steve means, I had an entirely different thought regarding global vs local.
And my thought was this: While we normally think of blogging giving you global reach, the realtor's treasure trove of knowledge about his local area is his crown jewel. It's almost 'local blogging with global impact'.
Except for maybe a city-specific restaurant blog, I think this is true more for real estate than almost any other industry. It's true that the market for a house is global (Someone for example, may buy my house just to have a place to stay during the Super Bowl next year. So getting my house in front of a geographically-dispersed bunch of potential buyers is important.
From the seller's perspective, my agent really needs to have her finger on the pulse of my neighborhood. She needs to pick up on trends long before they are significant enough to be statistical. Similarly, buyers need to leverage a different kind of knowledge posessed only by an agent who is really familiar with the area. (How good are the schools, for example).
A real estate agent-blogger needs to blog not only about her client's properties, but also about the neighborhood and local events. A good real estate blog focused on my neighborhood would give any prospective buyer a really good picture of what living here is like.
I know this is tangential to your point, Steve, but it is an interesting cooncept nevertheless.
