A good way to judge a blog is to see how often you want to leave a comment when you read it. When I read a post by Mocha Dad, I usually know halfway through that I will have something to say. Even if I don't always agree with everything he says, I always appreciate his honesty, his great writing, and his love for his family.
In many ways--and I get back to that every once in a while--I believe the "Everything changes when you become a father" warning is absolutely right, other than that it shouldn't be a warning. Your self-identity encounters a modified You, which you must learn to embrace and sometimes to forgive. Things change when you become a father, but your pre-fatherhood experiences will determine what kind of father you will become.
I think about that when I read Mocha Dad. I think you can truly see the man who has become a father and saw that as an opportunity to reflect on his life and to better himself. And you can see the way Mocha Dad uses his experience and the values he has inherited to guide him as a father and maybe more importantly, to guide the next generation in his care.
