Editor's note: The PowerBlog Reviews are officially one year old! This is the fifty-third in our regular weekly series.

The Smart Marketing blog by Jay Lipe brings you -- well -- lots of smart marketing information.

The title says it's located "at the intersection of small business st. & marketing ave." That's a great description of the virtual address and the blog's mission. Of course, in the real world Jay is located in Minneapolis, Minnesota, USA.

Jay is President of Emerge Marketing. He and his company provide marketing advice to small businesses.

As you might expect, Jay's blog is very good at providing marketing tips and advice to small businesses. Even compared with other marketing blogs it is especially useful. It is written in a clear and succinct style. All the information packs a punch.

This blog excels, however, in the way it is being used by Jay as a two-way vehicle.

This is where a blog leaves a traditional website in the dust.

A traditional website is a one-way conversation. Rarely if ever do you get a chance to receive input from a site visitor, other than perhaps taking an eCommerce order or a newsletter subscription. In fact, many traditional websites actually discourage communication and interaction, by making it hard to find contact information.

Not so with a blog. And Jay has figured that out.

Jay uses his blog to expand his knowledge base, to get fresh ideas and thinking from others. He tells me that one recent post, "Marketing a big ticket item," had just such an effect:

"After making the post, I heard from other experts in this area who added their comments to my post. Many of their points were good ones ... and ones I never would have thought of. As a result I came away from the exercise with more valuable information that I could end up using with my small business clients."
