Imagine a world where people could easily point their cell phone at you and give you a plus or a minus vote. If you let someone merge in, the other driver can give you a small star. If you stop and help someone with a flat tire, you might get lots of stars. If you cut people off or cheat on the carpool lane, you get bad karma. That's similar to PageRank. We all look at reviews for movies, restaurants, books, hotels, etc. And we look at the star rating on youtube, netflix, etc. Why not have it for people?

I endorse this idea!
It may make sense to separate the ratings along different axes: career, friendship, relationship. That way, a workaholic who ignores their significant other could have 5 stars on one axis and 0 stars along the other, as opposed to a confusing average of 2.5 stars.
To protect against spamming, you would enter a secret question for each category. Only people who are qualified to rate you would know the answer. For example, the work one could be "What is my desk location number?" so only your real coworkers could rate you.
Potential romance secret questions are left as an exercise to the reader.
This way, when my profile is posted, I won't immediately be voted down to 0 stars by thousands of angry Asian men.
