It's really unusual for us to hear from people who decide not to participate regarding the reasons why they are holding off, and this kind of information is perhaps even more useful to our efforts at continuous improvement than feedback from our current members.
I hope you take to heart any feedback from your current members. Another one of my concerns was how little activity I noted when I glanced at your user forum. I didn't read through it, just glanced at the volume and activity dates. Ditto for discussion on FB, which anyway has never struck me as a good context for serious discussion of issues such as the discussions you have no doubt noted here on KivaFriends with regard to Kiva.
We had always wondered to what extent Zidisha's inability to offer a legal guarantee that lenders' funds would be returned,
Not a factor for me any more than it is on Kiva. That doesn't mean I don't carefully consider the risks v. benefits.
the fact that financial gains from our loans might be subject to taxation,
Among others, I use MicroPlace - also taxed.
and the use of terms like "promotional gift" in our Terms and Conditions
and that does seem to be a current sticking point for me, doesn't it? Words are very powerful, as is their potential for misuse. Again, you can note here on KivaFriends the extent to which some of us go to get some wording changed and to resist other wording changes which we feel are not conducive to what Kiva is supposed to be and do.
Best wishes,
Paul
