Asked myself this question over the weekend actually. Just went through a huge purge of my RSS reader as I'm trying to shift more of my time and attention to what I'm calling "pillar content." Content that defines frameworks for a field. More Gary Halbert and Claude Hopkins and less Copyblogger and Content Marketing Institute. In general, I think that's a more valuable use of time and energy in the long run.
I stayed subscribed to your blog for a couple of reasons I think.
1. You - You're compelling, your story is interesting. The true value in blogs to me is the humanity and you allow yourself to be vulnerable and that's attractive and inspiring.
2. It's thought provoking. Though I often skim. I usually do reflect on what you write and compared with most content I consumer, it's more likely to force me to examine an existing framework or belief system in my own life.
I don't know what I want more of. I want to adopt more aspects of your mindset and so I think reading your blog drills some of that into me. You have some sociopathic (I mean that in the best way possible, not accepting the status quo) perspectives that I find fascinating.
