at the risk of being accused of self promotion i would say that sites with something valuable to offer can make that fact readily apparent by allowing their customers/visitors to review/rate their content. that's why i developed MAGPIE which is a customer review manager. adding reviewing capability to your site gives you an extra degree of credibility and enhances the site's stickiness, no matter what your business.
i don't know whether this program will catch on. it ought to. we'll have to see. it's not a new idea. on the contrary, it's a well-known one. but the ability to add this method of content collection so easily IS new.
why let players like Amazon and Epinions have all the fun?
