You need to have a ton of content to make any amount of money. After writing 200 articles, I started making a consistent $100/month. Not quitting my day job any time soon, but I have a lot of downtime at work, so it's a productive way to pass the time.
Oh, and the $100/month is pretty consistent. I took a month off from writing, and they still sent me money for the read time on my old articles. The pay is low... but my boss wouldn't send me a small stipend if I decided not to show up for a month. So, I really can't complain.
