There is a new UK based charity rating service called Intelligent Giving. Similar on the surface to Charity Navigator and Guidestar. They seem to have tried to take a fun attitude to the whole process. I like that the site makes it easy to explore for charities, rather than just look one up that you already know about. The “Experts’ Choices” and the “If you like this charity you might like…” sections reminded me of similar features on Amazon and iTunes.
