How would you say it's tedious? There are many sites with product reviews, blogs, forums, etc. Need a new camera? There's dpreviews. Need a new TV? Cnet. Need a new video game? IGN.
Well, don't be too enthusiastic about this idea.. I've seen lots of sites try it and fail such as Measy, Gdgt, etc. The ones that succeed are the ones that thrive in the search engines. People use search engines to find what they want.. they don't go to a specific destination.
