Coolness 0

I have rate many games already. I also rated many Least ratings games (instead of the default). I see that those getting very low rates are because they have coolness 0, which means they didn’t rate any other game.

What surprises me is that some of them are wondering why they don’t get comments on their games.

As I saw dozens of games with coolness 0, I was wondering if any dev have the actual number of games in that state.

Is this a problem with communication? I mean, maybe those who made a game don’t know they have to rate others to get their game rated as well. Or is it simple laziness? Can we do something to motivate these little guys to start rating other games?
