The best spinner & Unique article wizard. Why both??

Hey guys,

Please forgive me, I am very new to internet marketing. In the last week i have learned a lot. I run a number of different business and im now jumping into the online world where i seen a huge market in my niche with a very large hole.

So as well as employing the correct people i believe in learning as much as possible myself to make sure things run smoothly and add to the effect. The last week has been astonishing and i have learned a lot about SEO.

My question, 2 of the tools i have been recommended, Unique article wizard and The best spinner. Why use both? Initially i though 1 was just to submit and 1 just to spin. But i seen a video of a guy using UAW where it creates Unique articles by itself so why would the recommendation come to use both? I cant contact the guy who originally suggested i use both but he is a friend of friend who is really successful with online marketing so i am not doubting him at all.

Just looking for the difference between the 2 and the best way to use them in unison. Im a mac user but we have pcs here looks like ill have to break them out to make use of these services?

Thank you
