Do you dig the Diggable Ads?

Digg will be launching "diggable" ads this week, and we want to know if you like the idea.
Digg will be testing ads this week that let users Digg advertising. If users Digg your ad, voting the ranking up, your cost goes down. If users hate the ad, cost goes up (and probably shortens the run-time of the ad).
Digg is a great site, and I applaud them for trying to be on the cutting edge. So, here’s a quick rundown of both sides of the argument.
For: Digg is all about the sites users controlling the experience. If a Digg user likes an ad, there’s a good probability that more will as well, and more people should see that ad.
Con: Why would you want the good ads that are generating traffic to cost less?
So here’s our weekly poll: Are you for or against Diggable ads? Please, defend your choice in the comments.
