Hard to avoid the influence of the oil companies because they have enough money etc to ruin a campaign. Like cigarette companies, they are only interested in profits for their shareholders and to get the CEOs a maximum bonus.

I love the expressiveness of graphs (and also graphs themselves actually)!

Talking of graphs... a clip-o-graph of all Clipmarks users would be nice.
The more clips clipped, the bigger the images of the users. The lines could indicate who is following whom.

And a pop-o-graph: The more popped clips a user has, the bigger his/her image. The thickness of the (directed) lines may indicate 'how much a user popped clips of another'.

Since all this information is already public, it would not violate any privacy, would it?
