I agree with Henry (on the first part,
not on, "i can sometimes be narrowminded!").

What you're suggesting doesn't seems to add any lending functionality to what's already available.
As far as creating a "group" of individual lenders goes, that seems fine for the purpose of social networking. For example,
the Kiva page at Change.org allows for folks to show their support by joining and posting various types of comments and resources. I'm sure many schools, churches and other groups would find something like this valuable.
If you all do choose to go down the social networking road, I hope you also would implement a set of "friends" functionalities, e.g., adding friends and sending messages - public & private.
