I use whypark for a number of my domains. The problem that I have discovered with whypark.com is that their business model is flawed. As they get more successful their users get more UNsuccessful.
Why?
They use a database of free articles as their content. If you are the only site in your niche then you may not have duplicate content issues. However as soon as more sites are in their program and are in the same niche as you, then one of you has a duplicate content issue.
In general, it really seems like the only fast and low overhead way to do anything other than parking is to make mini content sites with original content and monetize with adsense.
I would be VERY interested if anyone has an automated way to generate unique content.
