Blogging can be as easy or as difficult as you make it. Your daily blog can be a short, but informative paragraph. It could be a relevant quote and your take on it. It could be important industry information, or an introduction to a new product with a customer code to use when purchasing it on a specific day.
Of course, some people do wish to write full articles for blogging .... professional writers for instance. But that doesn't have to be your blogging method. Write what you do .... talk about your products, your experiences, your company's accomplishments. Be real and be honest. People respect that. And if you want to add a little good-natured humor to your blog with an anecdote or funny industry story once in a while, that's good too.
