I think that is an art to get the point you want to make across to your readership in easy to absorb steps rather than a long winded dissertation.

Writing blogs too gets you to think more in depth of the subject matter you have an interest in as you know if what you write doesn’t stack up or make sense, you will either be ignored or on a more positive note create debate which in turn helps to inform you of other points of view which should if your attitude is right, further educate or broaden your perspective.

If you are writing about matters associated with your commercial skills, then by association of what you write if interesting and informative gets the readers to identify what your expertise is from which potential business might ensue.
