Personally, I think this is a great concept.
Nado, you're right... yet another way to pile up more debt, but... what a way to generate a source of revenue with little effort on the lender's part.
The creators of
Prosper and other services such as
Zopa have actually taken great measures to avoid scams, etc.
I think it's worth a shot. Start small and if it works well, toss more $$$ in.
Funny how this came up in the forums... I'm actually planning on experimenting with
Prosper in about 2 weeks and documenting the results on
my blog.
