GitHub is all about social coding. So today we’re rolling out a blob contributions box.

You can see it on every blob (file) view on GitHub. It’ll show you the last commit to touch the file and who’s contributed to that file. Check out some examples:

• Sinatra’s main.rb
• Backbone.js
• Gauges IntentConstants.java

The contributions box is a great way to get a feel for who’s involved in a project at a glance. Hope you enjoy!
