I dont care who writes my articles as long as they make me money. For me its crazy wasting time writing article when I get get someone else to do it. I just tell them what to write and where to place my keywords and thats it.
some people are just good at writing...my boyfriend spends hours and hours writing non stop answering messages and writing new articles, I guess you have to be born with it but you can also "fake it" somewhat, do a lot of research on what your going to write about...connect the random facts or whatever with personal experiences and let one thought "randomly" connect/drift off to another...
Most people just hire ghost writers. Outsources your articles writing to others is the best way if you want something fast and high in quantity.
I have been learning myself how to do this and I even tried a software before which seems to rewrite but I don't think it was any good.
