I'm still new to the entire blogging thing, even though I been doing it for years now, but I only recently really jumped into it.
But to your topic asking about writing your own articles, I use to worry about how the topic was wrote, so my idea was just finding a good article then copy it, spin it ect..
But after really wasting time messing with posting something thats been copied 10x over, I figured it didn't really matter what I wrote and just went with what I could type. I look up some small facts if I need to, and just fill in the rest with "bs". Instead of spending the time finding articles & spinning, I can write up about 5 articles in the time it would take to find one good one. And lets face it if your using a program to find articles for you to save time your still just using something thats been wrote before, and who knows how many times its been copied, how much gain can you get from a article thats been put out 20x over on the net?
So my tip is write what you can, and just throw in some facts & don't worry if it doesn't sound good. Unless you have a spelling problem, or cant type fast enough to write your self then I'd suggest doing the copy method. Or find a friend who has gone to college that can write good content for you.
