What do you mean? Where will this traffic be coming from?

Counting these framed pageviews as Digg pageviews is at least dishonest to advertisers and at most plain wrong.

According to Center Networks, the Digg toolbar is running Digg's Quantcast code. So it looks like they're going to try to do just that.

I mean that given the simplicity of how to use this (just prefix with digg.com), the number of stories dugg, and the level of interaction with Digg will both go up significantly. The toolbar (if we call it that) has Digg tools built in (related stories, etc...) and has sharing tools for Twitter, FB, email, etc. This is all designed to drive traffic to the main digg.com site.

does facebook's do the same?
