Yes. You are allowed to refuse to believe me. I still beg you would. Microsoft has a winner in a small free application called Windows Live Writer. The tool is essentially an offline editor for your blog posting, and WordPress and many other services are supported. And like me, even when you are the host of the blog on your own domain, not through a blog site.
The interface is simple to use, it is very WYSIWYG in the sense that it even downloads the style of your theme so when you write you will see how it looks, and thus avoiding WordPress’ awful awful web-based editor. It is a small application, it has many creature comforts and even allows you to write to multiple blogs.
