I think that negative feedback is necessary, because if I am looking into a product and can’t find any feedback on it, then I may assume that there haven’t been any major problems with it, and buy it, even though it sucks.

Unless something really got under my skin, I wouldn’t waste a lot of words or time on a post, but it’s good to know the bad and the good, and as a reviewer, if all you had on your blog was positives, then one may question your position on your reviews – are they biased or not.

Also it is (or should be) a good opportunity for the product vender to get some real raw feedback on their products (or services). If companies are monitoring the internet for their products, and find some negative reviews or trends, they then have an opportunity to fix these problems.

But like mama said – if you don’t have anything good to say, then maybe you should say nothing at all…
