We've just recently revamped the recommendations section of the site in order to produce better ratings and recommendations to you.
Under each post you can click on 1 of 5 stars to rate the posts interest to you. The more you rate the better the system learns your preferences and as a result will provide more accurate Recommendations for you.
Also a new little feature is that you can now directly do a Facebook Like under each post. If you're a Facebook user simply click the Like button under the post title and it will record your "Like" of the item just like it would on Facebook.
Give them a go and let us know of any issues in the comments.
