Do you want me to keep reading your journal?
Some people like the new LJ Navigation Strip, some people don't. Some people take the view that it's not polite to subject others to it.
If your journal shows the Navigation Strip, please go to the Viewing Options page and uncheck the box for "Always show the navigation strip to anyone who views your journal or community". This allows you to use the strip without imposing it upon anyone else.
Some of us have to use browsers in which we can't subvert the code that's used to display it. Some of us use devices where it swallows unacceptable quantities of screen real-estate, or browsers which it breaks and makes your journal or your entries effectively unreadable.
None of my regular journals, and none of the communities I maintain, display the Navigation Strip.
