GitHub was founded in 2008. The spike is in 2010-01. That's what the question mentions too.

I'd argue that GitHub became really good 2010-01. It takes a certain number of early adopters to group together before the social features finally become useful for everyone.

  That also happened to be the time when people REALLY wanted to use DVCS but Google Code lacks private repo ability and BitBucket was also getting really unstable. BitBucket was far more stable than Github the years prior to 2010. Mercurial also had a whole lot more GUIs to choose from and worked great on Windows. For the longest time Github just wouldn't send a tar ball when you clicked the download button. And then around 2010, BitBucket was doing a lot of stuff behind the scene and the service was down a lot. A lot of basic features just wouldn't work. They were probably getting ready to sell to Atlassian. I think that's the main #1 reason Git and Github took off. Another one is Linus' diatribe on SVN. That video on youtube's been viewed millions of times. The video really got the Linux fanboys jumping around all excited even though its command line interface sucks and didn't work quite well on Windows.

> Just to make clear, this graph show the installation of git on debian systems. Around the time the spike happens the Debian package was renamed from git-core to git. Maybe people found the package easier now that the name reflected the software. http://programmers.stackexchange.com/a/177892 http://programmers.stackexchange.com/a/177892

that is what network effects look like for eg. it is comparable to the chart of Facebook growth[0] [0] http://www.nathaninfocus.com/wp-content/uploads/2011/01/Facebook-Growth-Chart.jpg http://www.nathaninfocus.com/wp-content/uploads/2011/01/Face...

Before that time, git lacked http support, which means a large population behind firewalls couldn't use it. From memory, that happened sometime in December 2009, which correlates very closely with that graph.

Actually the spike is in 2010-04. I don't know that it's really related, but Drupal began switching from CVS to Git in 2010-03. I know a lot of people (myself included) looked at Git for the first time because of that.
