I don't think an anonymous rating system simply benefits 'cowards'....what it DOES do is eliminate retalliatory ratings, good OR bad.
As someone who can/does see the ratings I can say it takes a person who is not personally pre-occupied with his own 'status' or public success/perception to NOT become piqued and want to eke revenge. There's even the issue of "gee...Frogboy [example] gave it a '9'....he knows his stuff...ergo to be seen to know my stuff as well as he I better match his opinion/rating" [sad, but quite possible].
If someone gives me a '1'...when I 'naturally think its sheer brilliance personified' I just mutter 'what would he know, anyway?' and move on. I have enough 'fun' responding to others' concerns about THEIR works maybe being targetted unfairly to ever bother with my own.....
Building a better mousetrap is always the dream of the mad inventor...so devising a better 'rating system' is a frequent and popular topic for skinners/artists.
There really only is ONE real issue with ratings...and that is to devise a way to get MORE of them applied to each work/upload. The more there are the more 'accurately' the mean reflects the work's true appreciation.
OK...and since I was pedantic about 'only one'...the other issue is 'drive-bys'....people who just look at a bunch of works on a page and madly click 'buttons' to up their rating count...a self-serving act which only degrades the efforts of those who apply a rating critically.
A 'suggested' solution to this would be to recode the site to only have a work's rating button active in detail view...and perhaps then only once a download is activated.
This will put an effective stop to the drive-bys [by slowing the process].....but will also result in fewer [albeit maybe more reasoned] ratings being applied.
So....back to that 'only one' issue again....how to get a better mean through more rating applications? One 'help' was to weight rating effect via 'experience'...eg a Journeman's rating holds more sway than an Apprentice....but that only strengthens the 'professional/expert opinion' and does not always reflect a Joe-Average downloader's general concensus.
The only thing that'll do that is ratings .....lots of them.
Maybe quirky site-coding [T-Man will hate me] where the rating average is adjusted by some quaint formula of download count popularity....probably has its OWN issues...and isn't viable....but just a thought...
Perhaps we have a 'record' of how many ratings each person does in a given time...and if it ain't enough we send a goon squad around to their house to re-adjust their privates.....that'll work...
All I want is $10 dollars for every thread that references 'ratings' in its subject body....and retire to the South of France and take up wine drinking....
