Keep in mind, the new lenders should not make the mistakes we made in the first year. Most of the sour grapes in this forum are not because of the terrible mistakes we made the first year, but Prosper management style.
I lend on Kiva and get absolutely no interest. Out of $5k lent so far, not one default. Unfortunately, there are so many safety nets and escape clauses for Americans, we just don't seem to have the same moral attitude towards debt.
