Sorry, but I don't see the point. Colin, Sean or whoever has carefully selected a person as a reviewer for the site.
And yet beneath their review are the user reviews. I just don't see the point. Just because you can do something doesn't mean you should. The comments area was fine for people to have their say.
These user reviews just undermines the work the original reivewer puts in. I vote they should be stricken from the record (as it were) and comments only be allowed.
