Looks like I was wrong about the cutoff -
17 votes was the minimum requirement for ratings, not 20. This means only
555 entries are unrated.
Although I can understand your disappointment with your score, you should think about the people who didn't event got the 20 votes required to be ranked - I've tried to rate some of these games following "please save these games" posts on the last voting day, and some of them were actually quite good or interesting.
I don't know how games end in this state (I guess it's due to low coolness), but to me the most sad outcome for a game is no one playing it, isn't it?
Every single one* of the unrated entries' creators have rated less than 6 games themselves. 346 (62%) of them rated no games at all.
* The sole exception purposely unchecked all categories and as such did not receive any votes.
7 people got away with not voting on anything and still got into the ratings, because popularity trumps all and life is not fair.
