I really liked a recent post by Jack Vinson on Reputation everywhere or the growth of web based rating systems. He said that even Quicken, his personal finance system asks for ratings on vendors. He also mentions Epinions that lets individuals rate products they've purchased and links to any online vendors (and ratings of those vendors). Google builds its search on reputation as defined in large part by who links to whom and thus it favors blogs with high traffic and many inward links.
Menupalace covers Toronto restaurants and other venues. It has a forum where people can submit reviews. This is common on many food sites and travel sites. The wisdom of crowds is profilerating. I am sure there are attempts to game this system and when the crowd is small, the results can be more easily gamed or biased by a few. Rotten Tomatoes also you to rate movies. Newsvine allows you to rate news stories.
What’s next? Will the US Internal Revenue System ask us to rate the service providers whose services we deduct? Will the HMO ask for rating of health care providers? They may already. Digital technology makes all this much easier to do. What do you want to rate today?
