I am a huge fan of digg but have never used it for my own blog. I’ve also discovered newsvine. I’ve read a some posts and articles comparing them. I thought it might be nice to test the popularity of each.
I started registering in Newsvine some of my posts and a few hours later, I did the same on Digg. The result is impressive since Digg provided the same amount of traffic (still growing) in 4 minutes as Newsvine did in 10 hours.
I want to apologize for any inconvenient within both services doing the test. Indeed some Digg users have quickly discovered that I promoted my own posts and had to report it. Sorry for that.

[update] I’ve also reported my entries in Digg as spam since the test is conclusive (traffic mutliplied by 100).
[update2] It seems that Newsvine effect lasts longer that Digg like shows following figures:

It may be because Newsvine is still in Beta (as Brandon and Reggie commented) and has not as many shared posts/news as Digg has.

It is because newsvine is in a closed Beta. Duah. Anyone can visit digg

I must agree with Brandon above. To compare a public site to a closed beta is a flawed study.

Seems like you are comparing apples to oranges, Newsvine is still in its infancy. Wait until it’s had the publicity, and time on the market as digg. Don’t get me wrong I love both sites, and can’t see why they can’t work together.
