Its hard for me to blog because you have to value what you say enough to think other people may.  I value expert opinion in most things and so question blogging as I am not an expert.
Then I realized that was a completely unhealthy attitude and that I have things to say, right or wrong.  Useful or not.  Its healthy just to write them.  I have the will to power.  Less controversially; Cogito, Ergo Blog.
