My comments were mostly "meta". There has been a rash of entrepreneur bs here lately and I'm sick of it. I much prefer the NoSQL posts. However. To get to the meat of your post, I have personally (meaning, in my personal life) encountered issues with 1,3,6,9 which I have overcome to one extent or another. Or not. So whatever. Fuck it. I'm going to sleep. Good luck with your whatevers, I have to write a bunch of code tomorrow.
