If you take a picture of something happening on your street and write a blog post about it, you are not a journalist. If you wouldn't be granted press credentials for something, you're probably not a journalist. If it's a side gig you don't intend to make a living doing, you're very likely not a journalist.
There are plenty of instances where someone can fit into the article's definition of "journalist" where they probably shouldn't.
