Today, the company may have just revealed their big ace-in-the-hole for bringing in the revenue: a new ad platform called Digg Ads that will let users control which ads appear on the website by voting up or burying ads.
According to Digg, the more a user votes up an ad, the less costly the ad is for the advertiser. So, maybe if you get 100 diggs, your ad costs only half as much. On the other hand, an avalanche of buries will make advertising cost so much that you'll be kicked out of the system. The ads must appeal to Digg users, which hopefully will make these ads more acceptable to Digg's core user base.
The Digg Ads will be a new type of ad that appear within the stream. That means these adds will be mixed in with content, in between news stories and pictures of funny cats. Heck, these ads could be on the front page soon enough.
