I'm not that dude, but I read the article you are talking about and I somewhat agree with him. Although, I'm long term bullish, I reduced my position yesterday because I think it faces too many headwinds this month. It's OK to sell at a loss if you think it will continue to fall. You can always buy back in. My two big concerns are:
1) The stock could not hold its post-earnings pop value and appears to be in a slow decline (not at bottom yet)
2) The mega Facebook lockup that expires on the 14th of this month will drag ZNGA down with it.
I'll check back in two weeks. In five years either this company will be gone, or the stock will be over $12. I'm too conservative to invest too much in a sub $5 stock (although I am long GLUU).
