This is an interesting find I found about the Tag system.

After I discovered an old experiment without a follow up on the data I was extremely interested in the amounts of traffic StumbleUpon can truly bring a website. I will post follow-ups after each 100 thumbs up votes, and in return I will give two articles of yours a thumbs up as well.

We all know StumbleUpon is very fun to use, but how powerful is the traffic driver really?
