So I've been lax about checking my Prosper.com portfolio. Things have actually improved. The weighted ROI of 6.4% is below where I should be but not terrible. I would have done better in the stock market but only marginally better in a fixed income product. Indeed, given the 18 month average duration of this, it is slightly better than I could have gotten in a CD. Still, without the 12% expected return, I don't expect to be investing more at all.
