Actually, that is only the left corner of the Blogger navbar. You want to see the whole navbar, move your eyes up and you will see the whole navbar at the very top of this page. What I want to draw your attention to is "Next blog". That has both been a blessing and a curse - a blessing for those who just want to play "Chance" and it will almost be like playing at the roulette table. You wouldn't know what the next number will be. Similarly, you will get to "random" blogs which you may love or hate. It is a curse to educators who set up blogs for their students. Students clicking on "Next blog" may chance upon blogs with adult content, and that is horrifying to educators. Which is why many want to hide the navbar
Note that I wrote "random" blogs. Actually, it is not that "random". This "Next blog" gives preference those blogs just were recently updated. Which was why when I checked the visitor counter for Lewis Chew blog after publishing a new post, I found an increase in hits from navbar.
