Some of the site's oldest reviews don't have ratings for whatever reason. They used to be listed as N/A, but now they appear as 0/10 to fit into the new site design. If you look prior to 2006, a few have atypical ratings like .007/10 and X/10. I kind of wished there was an option not to include a numerical score, as I believe too many people skip the meat of a review just to see what the number is, and then complain that that figure doesn't fit their own.
I don't have to boost my review resume because I have a real resume.
