Wait, you don't know who the author is and you call yourself a tech recruiter?
Fred Wilson has invested in what, 100 tech companies? He has been writing MBA Monday's posts for years. This post has multiple hundreds of comments on it. There are probably hundreds of retweets and comments on Twitter about it (you know, another company he invested in).
I'm pretty sure he didn't need your blog post to give advice on hiring.
Actually I don't call myself a tech recruiter. Haven't done so in a while. That's a very old blog post and I am well aware of who the author is. A highly public personality doesn't preclude you to taking inspiration from other sources.
I'm not claiming the author lifted any of the content but I am curious as to whether or not he/she had read my post in the past?
