"What's Digg? Digg is a technology news website that employs non-hierarchical editorial control. With digg, users submit stories for review, but rather than allowing an editor to decide which stories go on the homepage, the users do."
I think we should think about allowing users to have the ability to add weight to posts here, in addition to assigning impact based on clicks. For instance, don't we want our important users to be able to tell us that a post represents an article that has a lot of weight.
Especially if we're thinking that people will have weights in addition to posts having weights.
