There's nothing wrong with using affiliate links as long as it doesn't influence the content of the article. The problem is that more and more reviews aren't really reviews. They're just rehashes of manufacturer marketing material masquerading as reviews. The junktification of the web is turning me to paying for content from sites like Consumer Reports.

Some Wirecutter articles have been really informing. Oddly, I rarely agree with their picks. But I've found the article comments invaluable to lead me to what should have been the pick.
