I personally have difficulty finding postings. While my resources do include the normal hiring places, I find that both the amount of "cybersecurity" posts in the normal places and the amount of "cybersecurity"-geared hiring places, are surprising low.
Maybe my difficulty lies in my perceived demand quantities versus postings I find.
With every HN Whos Hiring thread, I tell myself I need to write a tool to filter the posts based on buzz words, because scanning hundreds of the job openings for "security", "penetration", and the like is a major pain.
I've been meaning to read this www.gatesnotes.com/Books/Big-History-From-the-Big-Bang-to-the-Present but then found your comment for http://www.amazon.com/Sapiens-A-Brief-History-Humankind/prod... and now after reading the 1-star reviews from both, I want neither.
Good luck on your quest for a "purely subjective read". Every good book out there has its critics. I suggest you read this one and make up your own mind.
