Alright, I'm gonna follow John's lead and jump in this REALLY late!
I see a lot of suggestions for improvements. And I really like the labels that could be added (entertaining, paradigm-shifting, life-changing, informative, inspiring, helpful, etc.)
But since no one's playing devil's advocate, let me try.
Why are we so afraid of ratings? Why NOT have a system that rewards what the community deems excellent, and a system that lets others know when to "try harder"?
If I'm looking for help with marketing, I read the highest-rated articles first. (They ARE more helpful than the lowest rated articles, in terms of concepts, originality, helpfulness and readability.)
Ratings provide a helpful, quick clue to me as to what I might find valuable. I have gone through and read many of the highest-rated articles and have learned a LOT from them. (They are more helpful than almost any articles I have found in magazines.)
I have also read some of the lower-rated articles, to see if indeed they are not as good. The truth is, they're not nearly as helpful and they're not as well written.
I belong to an organization that lets us submit our original songs for critiques. I spent many hundreds of dollars recording my first demos and was very proud of them.
The message I got from the industry experts? A whole lotta "5's" sprinkled with some 6's and occasional 7's in the various categories (out of 10.) I got a big, huge "TRY HARDER."
And do you know what it made me do? It made me hire a songwriting coach. It made me try harder. It made me get feedback from every songwriter I respected. It made me re-write what I thoght were my best songs, and work with co-writers who knew things I didn't know.
Three years later, I'm a great F#@%*ing songwriter. And I still have room for improvement, and I still ask for feedback and re-write my songs.
The problem I see with a "liked it"! button or any other thumbs up approach is that is becomes a popularity contest. The more people you know, the more likely you are to have more readers and get more "points." I actually think the current rating system by numbers is MORE fair.
Hate the idea of having to comment to vote... if I don't like an article, I don't trash it (I have never rated an article below 5, and if I really hate it I just don't rate it) but I really don't want to have to justify why I'm not ranking something higher to the author. If people are afraid of low ratings, they'll be terrified by the critiques that might come with them.
Personally, I think it is helpful to have ratings, as both a reader and a writer. I'm fascinated with our indie-community rebellion on the matter. I do "get" it. I went to Evergreen State for awhile, the college with no grades. (And so maybe we allow people to submit articles without requiring ratings, if they don't want them.)
But just like our member "ranking" (how high up you are in the member roster based on your activity of various kinds), maybe the actual "number" the articles is ranked is a composite of many factors, including the readership, how many comments, how helpful members "rated" it (so the rating is only one piece of the "ranking"), and perhaps also if readers found it "inspiring" or "entertaining" or "paradigm shifting."
Thanks for all the thoughts... I love the rich feedback this question has brought up!
