Creating a list with twitter.com/yourusername/blog on the Twitter's recently launched feature, is a bad idea.
When create a list with slash blog then you will not able to see any pages of it. Actually, it is default when a user creates list with the term "blog", it redirects to blog.twitter.com. They did this to retain some power of the term "blogging".
But an interesting thing to say that you may list the user on that page but totally useless..
The above is the link i created to test it.. By clicking it you will sent to Twitter's official blog.
