The Ratings Feature
Ratings allow users to share an opinion about some form of content within the community. They might cast a vote in favor or against a particular blog post, photograph, or video.
Most networks have a ratings system of some sort. It could be a polar scale where things are good or bad. You may be familiar with Digg’s thumbs-up or thumbs-down system.
Other ratings systems are based on a quality scale, where one is the worst rating and the top number is the best rating. Things could be voted on with five stars or five cars, or whatever other icon makes sense for that particular network. You’re likely familiar with this from reading movie and restaurant reviews in your local paper.
