Echo JS 0.11.0

The libraries/projects I mentioned were only those which quickly came to my mind. Probably we would need to inspect a larger dataset in order to get meaningful results on the topic.

IMHO the reason why alot of single person projects gain traction at all is because they tend to have nice APIs. APIs which developers enjoy using. This is because those single persons have a clear picture in their head about how their library should work.
That's also why TJ has so many popular projects (in my opinion). It's because he does a great job designing the APIs. Funny thing is that he is also an actual designer :)
