I may have heard from them -- I've gotten a lot of queries about this
stuff... But tbh, I don't track it very closely, since all these
systems suffer from the same problems:
* The rich get richer
* Ideas thrive based on popularity and unpopular ideas are buried
* They require explicit human intervention to describe their users'
beliefs, something human beings are pretty bad at expressing (see
Metacrap for more: http://www.well.com/~doctorow/metacrap.htm
* They have no ready way of disambiguating their users' feelings
about one aspect of an item from another (e.g., I like this music
because the artist has CC licensed it, not because it sounds good)

Learn the Rapleaf Way (... and FAQ)
Rapleaf's goal is to make it more profitable to be ethical. To that
end, we're encouraging buyers and sellers to rate one another. You'll
build a reputation which will help commerce transactions go a little
bit more smoothly.
Rapleaf is all about rating individual buyers and sellers. We're about
rating people, not companies.
What type of feedback does Rapleaf gather?
Rapleaf tracks both quantitative and qualitative feedback on people. A
person is rated either "Positive", "Neutral", or "Negative". And
then a
rater is asked to give a more qualitative comment. For example:
I sold Steve some rare coins. He came to my house to pick them up.
He was on time, courteous (he took his shoes off to not muddy the
carpet), and paid in cash (and he had the exact amount). Steve even
gave me some tips about my other coins and told me what cleaners I
should buy for some new coins in my collection. I would do business
with Steve again.
Rapleaf Score and Stats
Rapleaf publishes three key scores -- the Rapleaf Commerce Score, the
Rapleaf Personal Score, and the Rapleaf Percent Positive.
Rapleaf Commerce Score: this is the most important score. This tracks
buyers and sellers transacting. We calculate the score by adding up
the
number of positive ratings and subtracting the number of negative
ratings. (Multiple ratings from the same person only count once).
Rapleaf Personal Score: this is the number of positive endorsements
(subtracted from any negative ratings) someone receives from someone
they know who can vouch for them. (Multiple Personal ratings from the
same person is not allowed). Buyers and sellers will often build a
Personal Score faster than they can build a Commerce Score.
Rapleaf Percent Positive: this is the percentage of ratings that are
positive.
I have a Rapleaf score even though I never signed up for Rapleaf. How
is that?
On Rapleaf, anyone can rate anybody. You do not need to be a Rapleaf
member to be rated. Rapleaf members can rate others and can interact
with their own rating.
