Blogcheating

As I get deeper into this cyberlife, I'm finding myself torn between online communities. Example: I wrote a review tonight of David Mamet's execrable Things Change on NetFlix, mainly because some new friends had joined my NetFlix community (shout out to Alder and Anson!) and I wanted my presence to be known. But then I thought: "I should post this review on my blog!" But it was too late. I had submitted it to NetFlix, which may not post it for two business days. Apparently, someone actually reads the things. The point being, is it somehow cheating if I copy my review from NetFlix and post it here as new content (which is precisely what I did with the Rescue Dawn review, below)?
