I created The Cantankerous Consumer so I could vent about the stupid things companies do to their customers. Instead of steaming about a negative consumer experience, I use the blog to express my dissatisfaction with the store or other business that doesn't seem to understand customer service.
In my career, I've always been focused on service. To me, my boss, my coworkers, our vendors... everyone is a customer. I treat them all the way I would want to be treated. It's actually easy to deliver good customer service, so I don't understand why so many people go out of their way to not do it. So, it's very frustrating to me when I am subject to bad service.
It's also very satisfying to enjoy great service. To be fair to all, I don't hesitate to let a company know when they've done a very good job. Or tell a manager that one of his or her employees did a really good job. As much as I write about bad service, I'm even happier to tell of good service.
So The Cantankerous Consumer was created to tell it all. And that's what you can do too. If there's a topic about which you like to write, and can write about often, then that's a topic which can be the subject of your blog. Regardless of what your topic is, there are going to be people searching for it (go ahead, enter anything into the free keyword tool and see how many people search for that). If they're searching, they'll find you. If they find you, your traffic will translate to ad clicks. That's how your cyber soap box will become your money maker.
