Reddit https://www.reddit.com. /r/sociallending is the primary subreddit though lightly used. I have also seen p2p lending discussions in /r/investing and /r/financialindependence.
Quora https://www.quora.com. The responders to questions related to P2P Lending, Lending Club, and Prosper (search keywords) on Quora tend to be industry participants and professionals.
Lend Academy Forum http://www.lendacademy.com/forum/index.php. This is the discussion forum exclusively related to all things P2P Lending. Most forum participants are individual investors in P2P Lending.
I have been lending on Lending Club and Prosper for over 4 years. I consider P2P Lending as part of my asset allocation to Junk Bonds.
I am attracted to these platforms as they enable direct access to an asset class, consumer lending, that was largely unavailable to individual investors previously. While debt segment is much larger than equities segment, individual investors have very little avenues to directly participate in debt/fixed income segments. P2P Lending opens up one such fixed income class - consumer lending. My primary interest with consumer lending is in the diversification aspects due to potential low correlation with other asset classes.
I enjoyed learning about consumer lending and other fixed income segments so much that in 2012 I started PeerCube https://www.peercube.com, an online crowd-lending analytics and automation platform.
I would not even bother starting without $5K or so. Since the minimum investment is $25, you need a large number of loans to offset any harm a few defaults can cause.
One word of warning: HN folks might have a tendency to get too geeky with the hands-on tuning, creating their own special lending rules to optimize returns. I would say don't bother. You are better off writing code for money and investing what you make.
Great point, thanks for underscoring that. 8% definitely beats the 1.5% I'm getting in a CD. Thanks!
