You can easily find the guy's LinkedIn. It appears that he is fully devoted to "entrepreneurship" rather than finding a traditional job, and currently lists himself as the founder of 2 current start-ups. So the unemployed part is basically by choice... and you'll notice, in the article, nothing stated about applying for jobs and not getting them.

I believe what this guy is referring to is that his startups currently aren't making money. And, to that end, this blog post is a marketing piece.
