Browsing my Google Analytics stats for the last month I noticed bit of a peak, waaaay more than the normal amount of traffic to my site. You can see the huge peak in the pic below, I mean really who wants to read stuff about me!
Digging around I see that the visits all came from StumbleUpon and were directed to one of my photos, it was one I took on Brampton Island in the Whitsundays a few years back, how cool.
Gotta love the unpredictability of StumbleUpon! You could quite easily get some more traffic from them as well too.
