Businesses still scratch their heads when thinking about how to build a blog for their business. It's often challenging to think about how to connect your product to the interests of consumers.

Let's say you make or sell refrigerators. You might say, "who would ever want to read a blog about refrigerators?" You might stop there and then dismiss this whole blogging thing altogether. Not if you're refrigerator-maker Sub-Zero.

This company, maker of ultra-cool refrigerators/freezers of all types (who can forget Owen Wilson bragging about his "twin Sub-Zs" in the movie Meet the Parents) decided not to make a blog about refrigerators (how many refrigerator enthusiasts do you know?). Instead, they recently created a blog about taking care of wine. I bet we all know several wine enthusiasts.

The blog is pretty cool--and sound from a marketing standpoint. It focuses on that which is of interest (wine) and then subtly touts that which protects that interest (their product). I think it's a great example of corporate creativity and corporate blogging that truly connects.
