Comparison of Shopping and Blogging

Shopping and blogging are two main activities in which people involve while spending their time online. Many people enjoy to shop and blog, so why not connect those two things together? I heard about a website where you are not only given a chance to compare thousands of product available online, but you also have an opportunity to blog about any product that you wish to blog about. Does this idea sound interesting and could websites like this become popular? It is difficult to say, but one disadvantage of this type of website is that people would need to do some work by writing a blog post instead of just relaxing by shopping.
