Of course, when it comes to Wallpapers, here on Wincustomize....getting a '1' for a rating isn't as 'bad' as may be imagined. Remember...it HAS made it past 'Moderation', where some pretty horrid things are left on the cutting room floor.
OK, some are upload errors....screenshots that fail, some are breach of copyright issues....some are 'stolen' works....but it's the rest....the ones that make you cry, and I'm not referring to their quotient of 'pathos'.
By and large, with the Wall dept., they are all pretty good, perhaps of diverse styles and taste and therefore not to everyones' equal liking, but they all have passed muster on some level or other....
One more thought on the non-anonymous concept of ratings... they [ratings] may be a lazy way of commenting on a skin but if associated with a signature they become a faster and perhaps more prolific method of giving/getting feedback.
If an artist reads...'Rated 1 by Treetog', he/she could perhaps request him to elaborate.
This happens with works that are moderated from time to time, so I can't see in real dramas doing it with this as well.
OK, if someone such as Treetog [because of his expertise in skinning] is swamped with requests of 'please explain' then perhaps it would have to be a no-obligation thing. After all, some of the people here are quite busy already and there's only 48 hours in a day...[I wish]....
