First thanks for the free article.
People know that I say what I mean so here it goes. I gave him to rewrite me an article about trading and investing(gold, stocks, bonds...) and it wasn't an easy rewrite.
What I like is the fact that the article is accepted by a site that is in top 2K sites in the world (DA77, PA81).
What I don't like, the article was rewritten sentence by sentence, which is not good, BUT to write an article on this topic, you need knowledge. And if you're earning by writing random content you can't know much about this topic. So, I don't see this as a major problem.
I was reading the article he gave to a Taxi guy and I like it. This is what I ask of my writers, to give some interesting story. No one wants article that is full of filler words. Nobody cares about 500 words of how awesome your cab company is, so he did a great job there. Writers often don't understand this, so they continue writing crap content
