I am currently using the latest devprev version of Foldit (Build ID 2012-03-27-48171M-win_x86-devprev). I have noticed quite a bit of network traffic when I run the application, so I jumped into the Resource Manager (System 7) to see where the traffic was headed. To my surprise, the Foldit app is communicating with sites like www.impulsedriven.com and taylorswift.wikia.com.
There is also traffic to foldit-webxx.cs.washington.edu, but that is quite small compared to the traffic going to the other sites.
What's up with those other sites?
