Question about managing your website
 

So I am on my web builder from Godaddy.com as most of you might already know about it. Anyways my objective is to make a viral website like Thechive.com, Viralnova.com, and boredpanda.com. But my question is how do they keep updating without redesigning their whole website, do they just use word press or something?

These websites are not run by a single person. A lot of people together make these websites possible.
And some of them might also use Wordpress.

yes, they use some advanced technology to achieve that goals....You can google it to learn more about it.....
