You are better off just experimenting with different areas of online income in your spare time. This is really weird that this question even popped up, because my fiancee and I were literally just talking about how her cousin went to school for journalism and still cant make any money online.
If you can write HALF WAY decent, which you can judging from your question, you dont need school.
You need to learn about SEO, keyword density/placement, traffic generation, authority backlinks and much more - but NOWHERE in this list of things you need is a college degree.
I am a full time internet marketer (who dropped out of high school) and I make a damn good profit. I love waking up to watch everyone else go to work while I just flip on my computer and see how much I've made as I slept.
Join a few marketing forums and just read other people's threads/questions/answers. I recommend www.ES5.com
You can't imagine how much you can learn just by browsing other people's threads.
Also, I recommend you get Tweet Attacks PRO & Tweet Attacks Account Creator, which you can get at:
Then I recommend getting ScrapeBox, which you can get at:
Those are LIMITED discount links.
It usually costs 97 but using those links it's only 57 dollars.
