A little bit of an update on the Stumble Testing

Using Stumbleupon buttons on my paper airplanes site was an interesting idea that I tried a few weeks back. It seems to be working pretty well. Below you see the graph of traffic I am getting from Stumble over time from the last big stumble spike (following which I added the stumble button).

For November (i.e. not including the spike in october) Stumbleupon now makes up 10% of my site growth and approx. 1% of all site traffic. I have a fair few ideas for how to boost this source of traffic even more and am really keen to give it a go soon!!!
