Pros: 1) Unlimited amount of recipes in all food areas. 2) An infinite number of reviews/ratings by novices & experts alike. Cons: 1) Cannot comment on a recipe unless you rate it, possibly skewering the ratings. 2) Ratings include those who have altered the original recipe (& most have). 3) Many irritating reviewers that drastically change a recipe, but won't submit their own. 4) Unlike other recipe sites, there is no indicator if a recipe is in the member's recipe box.
AllRecipes does have a graph of each recipe's ratings. However, it would be nice if broke it down to percentages too.
