Well, most people don't want to know much about Yarn. Granted, mostly because they don't even know it exists :)

What do you expect when Yarn has been out for less than a couple of weeks and this person isn't involved with the project in any way?

to not write an article proclaiming its everything?

Such is the problem with the majority of programming blog posts.

I expect the title to be something along the lines of "First thoughts on Yarn"

I was thinking the same thing. I want to know about the pitfalls and reasons not to use yarn. For example, does it support modules from github?
