blogs

What exactly is the point of a blog?
You write down what happens in your life, and people (some of which you might not even know) read all about it, like okay so a person in Utah, writes about how her kid learned to say milk (this is just an example) and some random rice factory worker in Japan reads about it??? WHAT? I don't exactly get it. If it's a way to tell people about your life, get their email address and email it to them. A blog??? What??? Is??? The??? Point???


Enlighten me.
