Updating sites
Easy updates are vital.
J ust adding a post or a page usually means adding the correct file in the correct place and running one command. New themes will make things a little more complex. You will have to check that it works; some themes will need other values filled in to create list pages and the main page.
When you are blogging, Hugo updates according to added files in the correct directory. You actually have the option of adding files or using the add command to add a new post. Except for being simple to do, when your site becomes big, you only want to update new content. In the case of Hugo and Jekyll, the default is to cache the content and do version updates.
