I thing blogging manually will do more good than autoblogging. That way, you have a lot of choices and free will to utilize your blog.
Auto blogging might be a source for passive profit, but most people will make very little money with auto blogging. I started an experiment and created a few autoblogs to see if/how much money they are making. After about 2 months, they are hardly making any money. Just my 2 cents... Better concentrate on blogs with real content and content that interests you so you are able to write about it.
