Kiva lets you lend to a specific entrepreneur in the developing world - empowering them to lift themselves out of poverty. See more on kiva.org.
Assume it as a joke: Just another Microblogging platform - that could be used to talk about your lendings.
Just a directory or linking between Kiva and Twitter - makes it a bit easier for lenders to talk about and helps to find other lenders. Or in other words, an idea to spread the word.
A TOK page showing your latest Twitter and Kiva activities.
