There are several recommendation pages these days that include slash, or specialize in slash. However, there aren't any pages that offer reviews and criticism. After the demise of the Slash Fiction Hall of Shame, I don't think there is any place on the net that dares to be critical. That site caused near-endless debates in the slash community. I think reviews and criticism are good things.
Discussion is good, debate is good, anything that makes people think is good.
Once the story is posted, you have absolutely no control over what people might say about it, privately or in public. The only way you can make sure that no one says anything about your story that you don't want them to say is by never showing it to them in the first place. This doesn't mean I believe that there are hordes of eager critics and reviewers out there waiting to pounce on any story that is offered, or that these critics and reviewers are mean and evil. For another, I don't think there is anyone right now who is prepared to face the wrath of the slash community by saying negative things in public about specific stories, when even negative comments about a type of story can get you flamed to a crisp by the defenders of said type. I'm not going to do it myself, for one.
