It looks interesting, but why is a sequence of users that vouch for the final user detrimental? User(1) would vouch for user(2), which should make user(2) more trustworthy, and therefor have greater voting power. Wouldn't this phenomenon simply stack as user(3) becomes more trustworthy because of the trustworthiness of user2? So that the final user, user(n) would be more trustworthy then a similar user who only had a sequence of two users, with the final one vouching for him? Besides that, however, it looks like a good idea, and i personally am interested in the final product.
