What are some of the reasons/features that made node.js, rails and bootstrap the popular watched repositories on GitHub?
As you can see at [GitHub][1]. The first place is node.js, the second Rails and the third is bootstrap. I've been playing with all of them for a while. But I'm still curious, what are the features or technological approaches that made them so attractive for developers/communities?
