Digg’s new social advertising platform prices ads based on popularity

If you’ve got a Facebook account, you may have noticed the option to like/unlike ads on your profile. Digg unveiled a plan today to take this concept a step further- charging less for ads voted up by Digg users.

With the new system, popular ads will get a lower cost per click rate while ads with more “buries” will be more expensive and likely pulled more quickly by media buyers. The new Digg Ads will appear within the content stream, marked as sponsored but otherwise mimicking regular Digg content.

Digg users are notoriously fickle, and speculation abounds as to how the community will react to the new ad model. (Such as mass burying all ads.) To gauge community and advertiser feedback, Digg plans to roll the system out slowly, starting with geek Digg-friendly sponsors Intel and EA.
