I know many PF blogs discuss Prosper, however I have yet to use it and will be incorporating it into my personal investments. Money lending though should be taken with the idea of how risky it may be. I know Prosper rates people, which is smart. However don't lend money you can't afford to lend. Pretty easy but some people get caught up in investments as one of their primary forms of income.
Anyway, I suggest you guys click the link I have at the top of the right side of my page just to see if it is for you. Like the ad says, you get a free $25 if you sign up to lend. Free money is always good.
