Blogs as customer communication?

It strikes me that blogs are an idea mechanism for dynamic customer communication, and the use of comments and ideal feedback tool. Yes a rudimentary search turns up very little information. An article in the Denver Business Journal, Shoestring Marketing, talks about the idea. Macromedia has a blog. Dynamism.com has one as well, though they don’t offer the option of comment.

Is it possible that this hasn’t become obvious to others? Everyday I see examples of poor customer communication, and it seems clear to me that blogs are a great answer to creating community. I’ll have to do a little more research and get back to you.
