Getting StumbledUpon
Just peeked at my referrers for my 2007 predictions post and amazed to see the amount of traffic the StumbleUpon service is driving in. In the last couple of hours I've clocked around 300 page views directly via SU. I've been StumbledUpon before, but I've not seen this kind of traffic come in before.
