How would creating generic (template, bland, unoriginal) blog post that has nothing to do with his business, written by someone outside of his business, have anything of relevant to with his business other then generic garbage that would not benefit or promote his business in any meaningful way, could possibly help promote his business? This whole concept is what one of those "professional" SEOs people came up with. You know that type, spent five minutes reading an article on SEO and now believe they qualify to give advice. This does not promote ones business. Generic articles ripped from Wikipedia and shoved into something that looks like a blog does not promote ones business.
Now, if you are absolutely set upon having a blog for your business, it should be about your business, how does your business function, what projects are you working on, how does your software work, and so on...Don't waste time out-sourcing people to write articles like "Cloud Computer Is So Awesome!!!!" when it is already covered by Wikipedia. Instead, you should be writing how your business does cloud computing different. The moment you start injecting generic gruff (ripped from Wikipedia) into your blog you remove the purpose of having a blog.
