Well, maybe the project he's working on is boring...
Considering the article pointed to was possibly one of the most trite, dull, uninformative things I have ever read, I am not surprised no one wants to get involved with the code.
But still, he does use bullet points, and I do admire his sense of pomposity:
"we shouldn’t be surprised if we get less contributors than we think"
Well, so what?
The world is not obliged to provide you with free time and resources just because you put stuff on github, at least make it interesting and, if you have to inflict "articles" on us, throw in a few jokes in at least, make it readable somehow!
