In an earlier story on how to "fly for free" a commenter was downvoted for explaining the entry contained affiliate links.<p>http://news.ycombinator.com/item?id=1428051<p>Most people who checked looked at the hover and the source -- but likely did not click the link.<p>The blog/whatever has direct links to the product page, but skimlinks.com highjacks the onClick event and redirected to the affiliate site.<p>Just FYI
