Improving usability Habrahabr: choosing a blog when posting a topic

If I do not have enough karma, I can only publish in my personal blog. However, “Which blog are we publishing?” Shows “my personal blog” in the drop-down list, which means that you can choose other blogs. But the blog is one. Choose from one thing - it is confusing and makes you think.

Why not remove the drop-down list when I can only write to one blog?
