I agree if you are looking to build a business then don't bother with auto content. You can get relevent articles from the article directories or even have someone write the articles for you. To think about it...you can just take plr articles and change them up a bit and then put them on your website. So its up to you. Are you looking for a long term business or make very little money short term
If you have a wordpress blog, then I would suggest Caffeinated Content. Just do a google search for them.
I'm going to second the majority of people here. Write quality content, give users something useful, and you will be rewarded. OR BE lazy, be unethical, steal others work, and you'll get what you rightly deserve.
