A few orders of magnitude? So at least 100x more? You might want to rethink that. sf.net gets more traffic today than github does. So, two orders of magnitude is most unlikely.

But most of the traffic to sf is just users downloading the software. If you were to look at the number of commits per day on sf v github, I wouldn't be surprised to see a x100 difference.

I don't know what's a valid source of traffic data but according to Compete you're absolutely right. I'm pretty surprised. It's also nice to see that their traffic has been trending upward.

You should have wagered.
