Pros
Once your article finally gets submitted, you do get paid within two days. You write about what you know, which is usually something that interests you. There are usually many topics to choose from. I can usually write an article in less than two hours, coming up to roughly $12.50 and hour, which isn't too shabby for an underemployed recent grad. Work from home on your own time.
Cons
The editors are the worst. There are who knows how many and they all have their own idea of what is right, despite there being general guidelines which everyone is supposed to adhere to. Most editors suggest edits that don't make sense and are grammatically incorrect. The pay isn't the best especially once editors are giving you ridiculous rewrites and telling you to leave out vital information because they don't understand it (which is obvious, the WRITER does the research, not the editors) and your $12.50/hour suddenly becomes much less. You can't be creative with your words so all the articles come out sounding robotic and boring. If you are able to just drone on and don't mind just writing for content and not for engaging, informational, factually correct, interesting writing, then I guess you'll love it.
