It is nice that you have taken time to suggest something new. However, I have to say I wouldn't want steemit to look so cluttered. This kind of 3x3 matrix can work for videos or something, but isn't the best choice for them either. The main problem with it is, that many of the articles would get lost due to human attention. It is much harder to browse through a list which goes left to right and left to right than it is a list that goes down.
Just my two cents. :)
Thanks, I will keep this in mind when I made my nexy vertion.
