It strikes me that as pretty as the Ripples feature might be it is fundamentally flawed because it doesn't actually list all the shares your post gets.
Presumably it is only using public shares, but since many people re-share to private circles it's missing 33% to 50% of the data.
Actually it doesn't even tell you as much as just looking at the "Shared" link on your post does because that at least tells you the name of the person who shared to a private circle.
