Because blogs benefit all human beings.
Here are three things blogging can do for you:
Backing up your stuff.
I have hundreds of drafts. I don’t intend to publish them all, but it gives me peace of mind knowing my hard work is saved somewhere safe. Especially since I fret about the original document getting deleted or misplaced. God forbid that ever happens to anyone.
Making you time manage.
Teaching you useful skills.
Like how to write. Or how to code. Even how to GIF. You don’t have to learn anything if you don’t want to. But you might as well.
Aren’t you glad you’re a blogger?
