I think points #2 and #3 are the most important thing. Even if are a great writer, if your potential customers aren't going to be reading your blog, the only person you are helping is your competitors. It just doesn't make sense to blog, you are putting your own ego ahead of the success of your company. If writing helps you do your job better, write to a journal. And if you think little bits of information can't help competitors, I strongly disagree. A little perspective (like where a company is focusing or where growth is coming from or whatever) can go a long way, and when you blog you are just leaking those things to everybody else.
