News sharing site Digg is taking a step toward creating an ad network that will include outside websites, Adweek reports. It’s a next step up from the cost-per-click program Digg instituted this summer, when the site interspersed ads among the streams of story posts. Like its posts, users were also allowed to vote on the ads, while marketers would be charged according to the popularity of their spot. This is also Digg’s first big advertising move since hiring Federated Media co-founder and publisher Chas Edwards as its chief revenue officer in May.
