I noticed that Zidisha doesn't publicize its low repayment rate (and the correspondingly high loss rate) very broadly - for example, on your frontpage. If you did, your forums probably wouldn't be filled with comments like these:
"The long-posted 98% repayment rate left me with a bitter taste. I feel both deceived and stupid." - mewesten
"I think you will not care at all when zidisha folds and you will not care at all at all the lenders loosing all their money. You will pat yourself on the back at all the money given to borrowers and what good work you did giving away other peoples money. Is it legal what you are doing? These are funds provided by members of the public it is not your money." - Russell
"If the model is to be sustainable, lenders must surely be made to feel that their interests are taken into account. They may choose to act as if they are in fact not lenders at all but givers - but that is not your advertised model, and would soon run into the sand in any case." - Wiredfox
"Your vision for Zidisha as a marketplace like ebay was a surprise for me to read in the forum. There is no clear explanation of this on Zidisha’s website. The impression I have had from the website is that Zidisha is just like Kiva and the others, except for the comments and low interest. It never occurred to me that no one was reviewing the business loan applications. I assumed Zidisha was somehow doing this." - Evelyn
These are your own lenders talking.
I think that if you explored some of the ideas I mentioned (e.g. featuring the repayment rate and loan loss rate on the frontpage, and adding a mission statement to the frontpage as well), you would see less angry lenders like the above.
