Writing a blog

I am currently using Evernote as a unified memo environment, it sync what I've written everywhere, I really appreciate of those cloud service. I realized that we shouldn't write everything using Evernote, I'll explain the benefit of writing that is open public.
First, the role of writing. That can be divided into 2 parts, writing for yourself, and for others. The former is to write to keep remember or study, organize your thoughts, etc. You intend to use that for yourself. And the latter one is that to impart what you have. Telling what you thought, felt, found to the others. That can effect, make others happy, and offend others. Therefore, writing for others is more responsible than the former one. And what truly you have to pursuit is to how well you can ten to the others. Not to mention, writing for yourself also matters, but with Internet, it is way better to be able to tell what you have effectively/efficiently/satifiablly to the rest of the world.
Now, the importance of writing public raise a question. How can we practice while we are not famous that nobody reads or poor at writing? One possible answer is to write your blog. Of course, basically nobody reads, but stay alert that you are writing that can effect people, you are writing that can visible to the people in the world. That kind of awareness make your writing public skills better. It requires ingenuity in order to make people understand.
