Why is the sudden increase in number of Git submitters on Debian popcon graph in 2010-01?
There's a big difference between an exponential increase (like we see with the facebook graph) and the original graph the question included. If that graph were to be believed, there's a dramatic discontinuity in the slope at a specific point -- that would imply some event that happened, not a network effect. And indeed, it sounds from other answers that this event was the package being renamed! :)
