Images, in order to be listed in the "top rated" list, need to collecte a certain number of votes. I observed that the images on top of the list are ALL adult-contents images, but I also noticed that other images in other categories have a higher vaerage rating but do not enter the top list because they do not have enough votes. Perhaps we could low the minumum number of votes required to be counted for the top list, put it maybe 20 or 15 votes. In this way also images of other categories could have the visibility that the adult contents ones have.
I know this would not represent the already cited "raise of taste" because the porn-party here is much bigger then other parties and would probably result in non-porn images to get low rating because members of the porn party will vote to low their ratings. I also know that many peopl from the non-porn party cannot, or do not want to, vote porn images in order to low down their ratings.
However I believe that lowing that limit will bring some "moevement" on the top list which could show to visitors a little more of the other side of plus613 the non porn side.
