I am new to kiva, only been around about 3 weeks. I do not understand how this has got blown so out of proportion. I was fully aware of the fact that I was not lending directly to the individual but that my pay back was based on a particular individual. I learned this on my own by reading and investigating kiva for myself. I made the choice to make several loans knowing how the system works and plan on making many more. I hope that this will blow over and people will understand that the system is working and helping many individuals and groups. The path that the money takes getting to and from is not the most important factor, the fact that the money gets there is the what counts. I think anyone who has invested any substantial amount should take responsibility for their lack of knowledge and lack of research. I am hopeful that people will look past all the negative and keep making a difference.
Yeah, I'm 3 months here rather than 3 weeks, but this is pretty similar to what I've experienced and how I feel about loaning on Kiva at the present. I've been doing a lot of reading about microfinance, and not just on/about Kiva. My Personal Microfinance Portfolio (thanks RichardF!) is still evolving, but Kiva will be a part of it as long as my reward -- peculiarly personal to me -- is equal or greater to the effort I put in and the risk(s) I feel I run.
However, I kinda have to agree there are some mixed messages going on. For example, I received Kiva's "maintenance" message momentarily while trying to log into the site just now. Maybe it should be updated a bit to correspond better with updated Kiva explanations elsewhere...
