I don't. I draft and finish up 90% of the blog post before I paste it into my blog as a brand new blog post.
I just find it too scary/unsafe to have blog "open" to be thinking and drafing for a few hrs. And it does take me several hrs. to a blog post.
Besides I have a copy of blog post elsewhere as backup.
The blog I need help with is cyclewriteblog.wordpress.com.
