Thanks for keeping us updated. This is really cool to watch. Did either of those domains have any PR before you started? How long have they been with WhyPark?
I thought about that extra advertising dollar too ...

great minds, eh?!
I wanted to get back to you too. There's an article in OMMA magazine that talks about the relevancy of repeat content. They say that for now, Google isn't really able to punish you for it ... but, they're working on it. Article is titled Double Double Content Trouble and it's in the Aug 06 issue.
Hope that helps!
